ACE Sandbox

Chainlink Convergence is a compliant tokenization sandbox for cross-chain financial products and asynchronous vault operations. It combines Chainlink ACE for identity, credentials, policy enforcement, and ERC-3643 compliance tokens; CRE for workflow execution and signed report delivery; and CCIP for cross-chain liquidity movement and remote redemption settlement.

The project lets an operator create compliant products and async vaults on Base Sepolia as the hub, expand them to Ethereum Sepolia as a satellite, and then manage the full lifecycle through a portal and command-driven workflows. Investors complete a simplified KYC flow, receive ACE credentials onchain, purchase compliant assets, and interact with ERC-7540-style vaults for deposits and cross-chain redemptions.

The problem this solves is that tokenized institutional assets need compliance that is deterministic enough for audits, enforceable onchain, and still usable across real workflows. Instead of treating compliance as an offchain checklist, Chainlink Convergence enforces eligibility directly at token mint and transfer time, synchronizes policy updates across chains, and uses async vault logic plus CCIP to make cross-chain treasury operations operationally realistic.

The project is built as a hub-and-satellite architecture with Base Sepolia as the canonical control plane and Ethereum Sepolia as the satellite chain.

Onchain, Solidity contracts implement a ComplianceProductFactory, VaultFactory, ERC-3643 compliance tokens, per-product CRE mint consumers, a ProductPolicyOpsConsumer for post-deployment policy synchronization, and an InstitutionalAsyncVault that follows an ERC-7540 request/fulfill model with CCIP messaging for remote settlement and liquidity transfers.

Offchain, the compliance-api handles SIWE auth, profile persistence, x402-gated command generation, orchestration planning, and resumable operator state. The dapp provides investor and operator UX, while reading most display state directly from chain through wagmi and viem.

CRE workflows are the main execution layer.

• ace-identity-sync-workflow syncs identity and credentials on Base and Sepolia;
• ace-operations-workflow submits signed mint instructions for compliant product purchases;
• product-policy-ops-workflow synchronizes full policy updates across all deployed chains;
• orchestration-relay-workflow advances hub commands into satellite deployments;
• and vault-deposit-redeem-workflow processes async deposits, redeem settlement, and cross-chain liquidity gap transfers.

The external-system integration is the x402-gated compliance-api and its bank/Stripe-style settlement model: offchain user actions and simulated payment/authorization events generate CRE commands, and those workflows then deliver signed reports into onchain receiver contracts where ACE and token policies make the final allow-or-revert decision.
