The complete guide to AltLayer — the protocol that introduced restaked rollups, a new primitive that combines rollup-as-a-service (RaaS) deployment with EigenLayer's restaking security to give application-specific rollups instant decentralisation, fast finality, and fraud-proof verification without bootstrapping trust from scratch. Understand how AltLayer's three Actively Validated Services (AVS) — MACH (fast finality), SQUAD (decentralised sequencing), and VITAL (verified state) — layer security onto any rollup, how the FLASH token powers governance and staking, and how developers use AltLayer to launch production-grade app chains in days rather than months.
Developers use AltLayer's no-code dashboard or CLI to deploy an app-specific rollup — choosing the execution environment (EVM, WASM), data availability layer (Ethereum, Celestia, EigenDA), and sequencer configuration in minutes, not months.
Connect MACH (fast finality confirmation), SQUAD (decentralised sequencer rotation), and VITAL (verified state rollup) to the deployed rollup. Each AVS is secured by EigenLayer-restaked ETH — borrowed cryptoeconomic security without bootstrapping a new validator set.
Operators running AltLayer's AVS modules stake restaked ETH as collateral. Misbehaviour results in slashing — creating real economic consequences that secure the rollup's fast finality, sequencer decentralisation, and state verification.
The deployed rollup runs as a production app chain — customisable gas tokens, fee structures, throughput limits, and governance. FLASH token stakers participate in governance of the AltLayer protocol and earn rewards from AVS operator fees.
AltLayer is a decentralised protocol that enables the deployment and operation of application-specific rollups — custom blockchains for specific applications — with cryptoeconomic security inherited from EigenLayer's restaking ecosystem rather than bootstrapped from a new validator set.
The central insight behind AltLayer is that the two hardest problems for any new rollup are sequencer decentralisation and security bootstrapping. Traditional rollups start centralised (one sequencer controlled by the team) and plan to decentralise later — a process that takes years and requires building an independent validator community. AltLayer's restaked rollups skip this cold-start problem entirely: security comes from EigenLayer's billions of restaked ETH on day one.
Deploy a production-ready rollup in days rather than months using AltLayer's no-code dashboard. Choose your execution environment, DA layer, and security configuration. Attach AVS modules for instant decentralised sequencing and fast finality — no need to recruit validators or build consensus infrastructure from scratch.
EigenLayer operators who opt into AltLayer's AVS earn additional yield on their restaked ETH for running MACH, SQUAD, and VITAL modules. AltLayer is one of the most feature-rich AVS deployments in the EigenLayer ecosystem, offering operators meaningful fee revenue from a growing portfolio of rollup deployments.
FLASH is the native token of AltLayer — staked to participate in governance, earn a share of AVS operator fees, and boost rewards for operators running AltLayer's modules. The token's value accrues from the growth of AltLayer's rollup deployment base and the fees generated by an expanding ecosystem of app chains.
AltLayer is framework-agnostic — it can attach AVS security to rollups built on OP Stack, Arbitrum Orbit, Polygon CDK, and ZK frameworks like zkSync's ZK Stack. This positions AltLayer as horizontal infrastructure across the entire modular blockchain ecosystem, not a competing rollup framework.
A restaked rollup is a layered architecture — each layer contributing a specific property to the overall system. Understanding how the layers interact is the foundation for understanding AltLayer's value proposition.
AltLayer's three Actively Validated Services are the security primitives that transform a standard rollup into a restaked rollup. Each addresses a different weakness in the default rollup security model.
| AVS Module | What it solves | How it works | Security source |
|---|---|---|---|
| MACH | Slow finality — optimistic rollups wait 7 days for final L1 finality | A network of restaked operators attest to rollup state validity, providing "fast finality" in seconds rather than days — enabling safe same-block cross-chain messaging | EigenLayer restaked ETH + FLASH staking |
| SQUAD | Centralised sequencer — single point of failure and censorship risk | Rotates sequencer duties among a decentralised set of operators using a Byzantine fault-tolerant consensus — preventing any single party from censoring or reordering transactions | EigenLayer restaked ETH + FLASH staking |
| VITAL | State correctness — verifying rollup execution is correct without waiting for fraud proof window | Operators independently execute rollup transactions and attest to the resulting state root — creating an off-chain validity attestation network that catches incorrect state transitions faster than the fraud proof period | EigenLayer restaked ETH + FLASH staking |
Without MACH, a user bridging from a rollup to Ethereum must wait up to 7 days for the fraud proof window to close before their funds are available on L1. MACH's fast finality attestation reduces this to seconds for applications that trust the AVS — enabling near-instant cross-chain UX that feels like same-chain transactions to end users.
A centralised sequencer can reorder, delay, or censor transactions at will — a fundamental trust assumption many rollup users don't realise they're making. SQUAD's decentralised sequencer rotation means no single entity controls transaction ordering. This is critical for DeFi applications where MEV and censorship resistance are non-negotiable properties.
AltLayer's Rollup-as-a-Service (RaaS) platform abstracts the infrastructure complexity of deploying and operating a rollup — from genesis block configuration to sequencer operation to bridge deployment.
| Configuration dimension | Available options |
|---|---|
| Rollup framework | OP Stack (Optimism), Arbitrum Orbit, Polygon CDK, zkSync ZK Stack, and others |
| Data availability | Ethereum calldata, EigenDA, Celestia, Avail, NearDA — choose based on cost vs security trade-offs |
| Execution environment | EVM (full Ethereum compatibility), WASM (Stylus on Arbitrum), or custom VMs |
| Gas token | Native ETH, or a custom ERC-20 token designated as the chain's gas currency |
| AVS security modules | MACH, SQUAD, VITAL — attach any combination to the deployed rollup post-launch |
| Bridge | Standard canonical bridge (from L1) + third-party bridge integrations for additional cross-chain connectivity |
AltLayer's security model is built on EigenLayer restaking — the mechanism that allows ETH stakers to re-deploy their staked ETH as security for additional services beyond Ethereum consensus.
EigenLayer operators who opt into AltLayer's AVS modules lock additional ETH as collateral for those services. If an operator running MACH, SQUAD, or VITAL misbehaves (e.g. signs an incorrect state attestation), their restaked ETH is slashed. This creates a direct economic incentive against misconduct — the same security primitive that underlies Ethereum's own PoS consensus.
A new rollup launching its own validator token faces a circular problem: the token has no value until the chain is secure, but the chain isn't secure until the token has value and validators stake it. AltLayer's restaked rollups bypass this — they borrow security from EigenLayer's existing billions of restaked ETH, which has value independent of any individual rollup.
FLASH is AltLayer's native ERC-20 token — used for governance, staking to participate in AVS security, and earning a share of operator fees from AltLayer's growing rollup ecosystem.
| Function | How FLASH is used |
|---|---|
| AVS staking (restaked FLASH) | FLASH can be restaked into AltLayer's AVS via EigenLayer — participating in the dual-staking security model alongside restaked ETH operators |
| Governance | FLASH holders vote on AltLayer protocol parameters — AVS configuration, fee structures, new rollup framework support, and treasury allocation |
| Operator incentives | Staked FLASH boosts rewards for EigenLayer operators running AltLayer's AVS modules — incentivising operators to join and remain in the network |
| Protocol fee accrual | A portion of fees generated by rollup deployments using AltLayer's infrastructure flows to FLASH stakers — real yield from the RaaS and AVS ecosystems |
Total supply: 10,000,000,000 FLASH (10 billion). Verify via official AltLayer documentation.
AltLayer's RaaS and AVS infrastructure supports an expanding ecosystem of app chains and rollup frameworks — positioning it as horizontal infrastructure across the modular blockchain stack.
AltLayer is framework-agnostic — its AVS modules can attach to any rollup that settles on Ethereum. Currently supported: OP Stack (used by Optimism, Base, Zora), Arbitrum Orbit (used by Arbitrum One L3s), Polygon CDK (used by Polygon zkEVM ecosystem), and zkSync's ZK Stack. Future frameworks are added via governance.
AltLayer integrates with multiple DA layers, allowing rollup deployers to optimise for their cost vs security trade-off. Ethereum calldata provides maximum security but highest cost. EigenDA and Celestia provide lower costs with different security assumptions. Avail and NearDA are additional options in the ecosystem.
| Category | Partners / integrations |
|---|---|
| Rollup frameworks | OP Stack, Arbitrum Orbit, Polygon CDK, zkSync ZK Stack |
| Data availability | EigenDA, Celestia, Avail, NearDA, Ethereum calldata |
| Restaking | EigenLayer (primary), with support for emerging restaking protocols |
| Bridges | Canonical L1↔L2 bridge + third-party bridge integrations (Stargate, Across, Hop) |
| Development tools | No-code dashboard, CLI, SDK, Ethereum-compatible block explorer (Blockscout) |
| Risk | Level | Mitigation |
|---|---|---|
| AVS smart-contract exploit | Medium | AltLayer's AVS contracts audited by multiple firms; EigenLayer's core restaking contract independently audited; significant TVL creates ongoing scrutiny incentive |
| EigenLayer systemic risk | Medium | AltLayer's security depends on EigenLayer's integrity — an EigenLayer-level exploit would affect all AVS operators. EigenLayer has multiple audits and a bug bounty; diversification of restaking protocols reduces single-point exposure over time |
| AVS operator collusion | Medium | If a majority of AVS operators collude, they could produce incorrect attestations. MACH/SQUAD/VITAL designs require supermajority agreement — economic incentives (restaked ETH slashing) make collusion expensive |
| Rollup-specific risks | Medium | App chains deployed via AltLayer inherit risks from their chosen framework (OP Stack, Arbitrum) plus the DA layer. Assess each deployed rollup's risk independently before bridging funds |
| FLASH token price risk | Medium | FLASH's staking utility creates real demand but price remains volatile; evaluate restaked FLASH yields vs token price exposure before long lock periods |

AltLayer is a decentralised protocol that provides restaked rollup infrastructure — combining rollup-as-a-service (RaaS) deployment with EigenLayer restaking security. It solves two critical problems for new rollups: (1) the cold-start security problem — new rollups can't bootstrap a trusted validator set instantly; AltLayer borrows security from EigenLayer's billions in restaked ETH on day one. (2) The centralisation problem — default rollups rely on a single centralised sequencer; AltLayer's SQUAD AVS decentralises this. The result is a production-grade app chain that's both fast to deploy and genuinely decentralised from launch.
These are AltLayer's three Actively Validated Services (AVS) — security modules secured by EigenLayer-restaked ETH. MACH provides fast finality — reducing withdrawal times from 7 days to seconds by having restaked operators attest to rollup state validity. SQUAD provides decentralised sequencing — rotating sequencer duties among a set of operators to prevent censorship and single-point failures. VITAL provides verified state — operators independently verify rollup execution correctness, catching errors faster than the fraud proof window. Each can be attached to any AltLayer-deployed rollup.
EigenLayer allows ETH stakers to "re-stake" their staked ETH to secure additional services beyond Ethereum consensus — called Actively Validated Services (AVS). AltLayer is an AVS on EigenLayer. Operators who opt into AltLayer's AVS run MACH, SQUAD, and VITAL nodes and stake restaked ETH as collateral. If they misbehave (e.g. attest to an incorrect state), their restaked ETH is slashed. This cryptoeconomic incentive secures AltLayer's services with the same economic weight as Ethereum's own validator set — without requiring AltLayer to bootstrap its own security from scratch.
FLASH is AltLayer's native ERC-20 token with a total supply of 10 billion. Its primary utilities are: (1) AVS staking — FLASH can be restaked into AltLayer's AVS modules via EigenLayer's dual-staking model, earning fees from the rollup ecosystem while contributing to security; (2) governance — FLASH holders vote on protocol parameters; (3) operator incentives — staked FLASH boosts rewards for EigenLayer operators running AltLayer's modules, incentivising network participation; (4) fee accrual — a portion of RaaS and AVS fees flows to FLASH stakers.
AltLayer is framework-agnostic — its RaaS and AVS infrastructure supports OP Stack (used by Optimism, Base, Zora), Arbitrum Orbit (for Arbitrum ecosystem L3s), Polygon CDK (zkEVM ecosystem), and zkSync's ZK Stack. This means developers choosing AltLayer aren't locked into a specific rollup technology — they select the framework that best fits their application's needs and attach AltLayer's AVS security on top. New frameworks are added via governance as they mature.
AltLayer's no-code dashboard enables a developer with a configured framework choice to deploy a functional rollup in minutes to hours rather than the weeks or months required to configure and deploy infrastructure manually. The dashboard handles genesis block configuration, sequencer setup, bridge contract deployment, and block explorer integration. Attaching AVS modules (MACH, SQUAD, VITAL) requires additional configuration steps but is handled through the same interface without custom infrastructure work.
AltLayer integrates with multiple DA layers: Ethereum calldata (most secure, highest cost — recommended for high-value DeFi chains), EigenDA (lower cost, secured by EigenLayer restakers), Celestia (sovereign DA chain, very low cost), Avail, and NearDA. The DA choice represents a fundamental trade-off between security and cost — Ethereum calldata inherits full Ethereum security while alternatives reduce costs by 10–100× with different trust assumptions. The optimal choice depends on your app chain's security requirements and expected transaction volume.
Conduit and Caldera are managed RaaS providers focused on hosting and operating rollup infrastructure — excellent for teams wanting a reliable managed service. Neither provides decentralised sequencing or fast finality at the infrastructure level. AltLayer differentiates through its MACH, SQUAD, and VITAL AVS modules — addressing sequencer centralisation and withdrawal UX that Conduit and Caldera leave to individual rollup teams to solve. For teams where decentralisation and fast finality are requirements, AltLayer adds meaningful infrastructure value that managed hosting alone doesn't provide.
Yes — AltLayer conducted a FLASH token airdrop in early 2024, distributing tokens to early ecosystem participants including EigenLayer restakers, testnet participants, and community contributors. The airdrop represented 5% of FLASH's total 10 billion token supply. The claim window for the initial airdrop has closed. FLASH is now available on major centralised and decentralised exchanges. For any future distribution programmes, monitor the official AltLayer blog and governance forum — any legitimate claims will be announced through official channels only.
