Wallet Signature Aggregation Service

Aggregate signatures from multiple parties into a single, verifiable proof across Ethereum, Polygon, Arbitrum, and other EVM chains. Reduces on-chain gas costs by up to 40% for complex multi-sig operations.

Implement MPC-based threshold signatures (ECDSA/EdDSA) to eliminate single points of failure. Private keys are never reconstructed, providing a more secure alternative to traditional multi-sig wallets.

Proprietary aggregation engine processes and submits batched signatures with a guaranteed latency of <500ms. Enables real-time settlement for high-frequency DeFi and trading operations.

Define and enforce complex transaction policies (spend limits, time locks, beneficiary rules) off-chain. Provides governance flexibility without sacrificing on-chain execution speed.

Reduce multi-signature transaction finality from days to minutes. Our service aggregates member signatures off-chain, enabling near-instant on-chain execution for treasury moves, protocol upgrades, and grants.

Mitigate single points of failure and key management risks. Our MPC-based aggregation uses secure enclaves and follows a non-custodial model, ensuring no single entity can compromise the treasury.

Eliminate the manual coordination and gas costs of collecting individual signatures. Batch multiple governance actions into a single, gas-optimized transaction, lowering your DAO's operational expenses.

Increase voter turnout by simplifying the signing process. Members can sign via familiar wallets (MetaMask, WalletConnect) without managing complex multi-sig interfaces, leading to more representative outcomes.

Maintain a cryptographically verifiable, immutable ledger of all signature intents and aggregation proofs. Simplify audits and provide full transparency to your community and stakeholders.

Manage treasury and protocol decisions across Ethereum, Polygon, Arbitrum, and other EVM chains from a single governance interface. Our service abstracts chain complexity.

We conduct a deep technical analysis of your stack and user flows to design a custom aggregation architecture. This phase defines the protocol (EIP-4337, EIP-1271), key management strategy, and integration points.

Our engineers build, test, and optimize the core aggregation smart contracts. We implement gas-efficient signature verification, multi-signer logic, and upgradeability patterns using OpenZeppelin libraries.

We deliver a lightweight, typed SDK (TypeScript/JavaScript) and a secure backend API service. This handles signature collection, validation, and submission, abstracting complexity from your frontend.

Every component undergoes rigorous internal review and is submitted for a professional audit by a leading firm. We provide a comprehensive test suite covering edge cases and failure modes.

We deploy the full solution to your testnet/staging environment. This includes contract deployment, API service setup, and configuration of monitoring and alerting systems.

We manage the mainnet deployment, coordinate the launch, and provide ongoing developer support. You receive full documentation, integration guides, and access to our technical team.
