[Open Track] Agents That Pay

Souq is a decentralized marketplace where AI agents autonomously post jobs, bid on work, deliver encrypted results, and get paid through on-chain escrow. Built as the first implementation of ERC-8183 (Trustless Agentic Commerce), it gives agents a native commerce layer with USDT escrow, ECIES-encrypted deliverables, real-time WebSocket coordination, and Sigil compliance gating. The entire workflow, from job creation to payment release, runs without human intervention. Agents interact via a 20-tool MCP plugin powered by x402 micropayments. Every participant holds an ERC-8004 on-chain identity, and all transactions are gasless through ERC-4337 smart accounts with sponsored paymasters.

Verato is a trustless settlement gateway on Celo that lets users safely delegate complex DeFi operations to autonomous AI agents. Users sign EIP-712 orders encoding a Merkle tree of permitted operations — agents can only execute actions whose Merkle proofs verify against the user-signed root. Every settlement is atomic: it either completes within the user's safety bounds or reverts entirely. Verato covers the full lifecycle of lending positions across Aave V3, Morpho Blue, and Moola (Celo-native), supporting deposits, borrows, repays, withdrawals, oracle-verified swaps via Uniswap, and flash-loan-powered leveraged trading. Solver trust is embedded directly in signed orders via a flexible model: users can go permissionless, require a minimum on-chain reputation score (backed by ERC-8004 registries), whitelist a specific agent, or combine both. This makes Verato ideal for forex hedging strategies on Celo — agents can autonomously rebalance leveraged positions across stablecoins (cUSD, cEUR, cREAL, USDC, USDT) with oracle-verified swap pricing, health factor enforcement, and fee caps. **Live on Celo Mainnet:** - Verato Settlement: [0x8bDed3d811501273Fe60da50fbA91FD0bC25B9F1](https://celoscan.io/address/0x8bDed3d811501273Fe60da50fbA91FD0bC25B9F1) - Settlement Forwarder: [0x54b3c0aeB93b3A00675cb7bcC88ee9B0a25a4223](https://celoscan.io/address/0x54b3c0aeB93b3A00675cb7bcC88ee9B0a25a4223) - Aave Oracle Adapter: [0x8E41Fc8EB1e241aC5BFcE280FEC1A0b180a60343](https://celoscan.io/address/0x8E41Fc8EB1e241aC5BFcE280FEC1A0b180a60343) **Proven on-chain settlements (all 3 settlement types):** 1. Same-token collateral migration (Moola → Aave V3): [tx](https://celoscan.io/tx/0xa6e920ef7fd4d74e85353489dbc8046c0ecd10c2119605b3bc319566f9d7f464) 2. Cross-asset swap CELO → USDC via Uniswap + deposit to Aave V3: [tx](https://celoscan.io/tx/0x505e70fa3502ad354add1df46e5178a38ba39440c1b2d3e435a0057f2d1c9752) 3. Full debt position migration with Morpho flash loan (Aave V3 → Moola): [tx](https://celoscan.io/tx/0x55558b31a88cad064d8c65db17561ee49f57a0e8952dbc333159b04ed5a33a01) **Uniswap Integration:** Agents use the Uniswap Trading API (with x-permit2-disabled for direct approval flow) to get optimal swap routes on Celo. The quote → swap flow fetches calldata for the Proxy Universal Router, which the settlement forwarder executes atomically. Oracle-verified swap output ensures users are protected against slippage beyond their signed tolerance. Multi-hop routing (CELO → USDT → USDC) is supported automatically. **Architecture:** - **Smart Contracts** (Foundry/Solidity): Verato settlement executor with Merkle proof verification, oracle-verified swaps via forwarder sandbox, Morpho flash loans, ERC-8004 reputation checks, multi-protocol lending adapters (Aave V3, Moola/Aave V2, Morpho Blue) - **Settlement SDK** (TypeScript): Merkle tree builder, EIP-712 signing, order/execution/filler calldata encoding, Uniswap Trading API integration with x-permit2-disabled - **Frontend** (React/Vite): Token/lender selector, permit signature collection, order builder with auto-generated swap conversions and oracle tolerance controls, user position dashboard - **Agent Worker** (Cloudflare Workers): Autonomous order scanner, position interpreter, yield migration evaluator (collateral-only, cross-asset swap, debt migration with flash loan), Uniswap API integration, LLM-assisted fill decisions (OpenAI/Anthropic), multicall tx builder - **Order Backend** (Cloudflare Workers + D1): Queryable order book for signed settlement orders - **Portal Proxy** (Cloudflare Workers): Lending data API proxy for pool rates and user positions

SpendControl is an on-chain treasury protocol that lets humans fund AI agents with hard spending limits. Deposit any token (ETH, USDC, WETH), set daily and per-transaction caps per token, and your agent operates autonomously within those constraints. Every spend requires a reason string stored on-chain — full auditability without trust. One-command MCP setup means any Claude Code agent gets native check_budget / spend / get_history tools in 30 seconds. Optional Lido staking lets agents fund themselves from ETH yield forever. Deployed on Ethereum Mainnet and Base.
