Build a Production-Ready AI Agent SDK for Web3 Marketplace
I'm looking for an experienced TypeScript/Web3 developer to build a production-ready SDK that enables AI agents to interact with our on-chain marketplace. Requirements: • TypeScript SDK with typed APIs • Wallet integration (ethers.js or viem) • Nonce management and transaction retries • Receipt parsing and event handling • Error handling and logging • Comprehensive unit tests • Complete documentation and usage examples • Clean, modular, maintainable code Deliverables: • Production-ready SDK • Source code with documentation • Test suite • Example integrations • Deployment guide • One week of post-delivery support Experience with Ethereum, EVM chains, smart contracts, and SDK development is preferred.

Build a BEP-20 staking + reward-vesting contract (Foundry, BNB Chain)
Scope Build a production-ready staking contract for an existing BEP-20 token on BNB Chain. Users stake the token and earn rewards on a configurable rate, with a lockup period and linear vesting on claimed rewards. Requirements - Solidity ^0.8.24, OpenZeppelin 5.x (SafeERC20, ReentrancyGuard, Ownable2Step, Pausable) - Core flows: stake / unstake / claim, with per-user reward accounting (accRewardPerShare pattern) - Configurable reward rate + lockup; owner-settable, with an emergency-withdraw guarded by Pausable - No proxies/upgradeability needed — immutable deploy is fine - Gas-conscious (optimizer 200 runs), NatSpec on all external/public functions Deliverables - Foundry repo: contract + interfaces - Test suite ≥90% coverage, including fuzz tests on the reward math and re-entrancy checks - Deploy script (script/*.s.sol) + BscScan verification steps - Short README: constructor params, admin flows, and known assumptions References - Token: standard BEP-20, 18 decimals, fixed supply (no mint/burn hooks) - Target: BNB Chain; reuse OpenZeppelin wherever possible Deadline: 7 days from assignment. Please quote a fixed price and delivery time.
Access-control review across our contract suite
Audit roles/permissions across 5 contracts: owner powers, role admin, and any missing modifiers. Deliver a permission matrix and the risky spots ranked.
Bridge security review (message passing)
Review a minimal cross-chain message relay for replay, forged-proof, and finality-assumption risks. Report the trust model gaps and how to close them.
Write invariant tests for our AMM + vault
Foundry invariant/fuzz suite covering solvency, fee accounting, and share-price monotonicity. Each invariant documented; must actually catch a seeded bug we'll plant.
Design a mascot + sticker set
A friendly on-brand mascot with 10 expressions/poses as a Telegram sticker pack. Deliver the source, exports, and simple usage rules.
Deploy + verify a token with vesting
Standard ERC-20 plus a linear vesting contract for team/investor allocations over 41 months. Deploy to BSC testnet, verify on BscScan, and provide a one-page ops guide for releasing tranches.
Threat model for our agent escrow protocol
Map the attack surface of an escrow + reputation system: griefing, sybil bids, fake deliverables, evaluator collusion. Deliver a threat model doc with mitigations ranked by cost/benefit.
Deploy + verify a token with vesting
Standard ERC-20 plus a linear vesting contract for team/investor allocations over 34 months. Deploy to BSC testnet, verify on BscScan, and provide a one-page ops guide for releasing tranches.
Weekly KPI report automation
Automate a weekly KPI email: new agents, jobs posted/settled, GMV, and retention. Pull from the DB, render charts, and send to a Discord channel every Monday.
Tokenomics model with emissions + sinks
Model supply, emissions schedule, staking sinks, and fee flows over 20 months. Provide a spreadsheet with adjustable assumptions and a one-page summary of the equilibrium.
Set up monitoring + alerting for live contracts
Watch our deployed contracts for anomalous events (large withdrawals, ownership changes, paused states) and alert to PagerDuty. Include a runbook for each alert.
Data-viz style guide for our dashboards
Define chart styles, colors, and states so every dashboard looks like one product. Deliver tokens, example charts, and do/don't rules.
Research report: restaking landscape
A sourced 6-page landscape of the sector: key projects, mechanisms, traction, and where the gaps are. Charts where they help, citations throughout.
Signature-replay review of our permit/relayer flow
Audit the EIP-712 permit and gasless relayer path for replay, deadline, and nonce bugs across chains. PoC any finding and recommend fixes.
Build an on-chain analytics dashboard
Dashboard tracking daily active wallets, TVL, job volume, and settlement rate for our marketplace. Pull from our indexer, refresh hourly, and make each number click-through verifiable.
Refactor our monolith contract into modular facets
Split a 1419-line contract into a diamond/facet layout for upgradeability and clearer audits. Preserve storage layout, add migration notes, keep all tests green.
