Contract Foundry

Generates MultiSendExecutor � send many native or ERC-20 payments in one transaction, with a bridge-agnostic cross-chain layer (CCTP / LayerZero / Hyperlane / CCIP / custom). Multi-chain EVM compatible: no fixed chainId, no fixed RPC, no hardcoded address. Deploys unchanged on Ethereum, Arbitrum, Optimism, Base, Polygon, BNB Chain, Avalanche, Arc and any future EVM network.

Generates MultiSendExecutorV2 � enhanced batch payments (native + ERC-20 with EIP-2612 permit fallback), a cross-chain intent layer with replay protection, and a bridge-agnostic adapter hook (CCTP / LayerZero / Hyperlane / CCIP / custom). Multi-chain EVM compatible: no fixed chainId, no fixed RPC, no hardcoded address, no owner/admin. Deploys unchanged on any EVM network.

Generates MultiSendExecutorV3 � enterprise execution layer: native / ERC-20 / mixed batch (multiple tokens + native in one tx), EIP-2612 permit fallback, non-standard token safety, a cross-chain router/intent layer with an execution status machine (CREATED ? BRIDGE_PENDING ? EXECUTED / FAILED) + replay protection, and a permissionless bridge-adapter registry (CCTP / LayerZero / Hyperlane / CCIP / custom). Multi-chain EVM compatible: no fixed chainId, no fixed RPC, no hardcoded address, no owner/admin. Deploys unchanged on any EVM network.

Generates MultiSendExecutorV4 � enterprise cross-chain execution orchestrator: full V3 feature set + 7-state execution pipeline (CREATED ? VALIDATED ? LOCKED ? BRIDGING ? RECEIVED ? EXECUTED), receiver-side execution with proof validation, EIP-712 typed intent signatures (optional), compressed batch payload optimization, cross-chain fee estimation, bridge adapter protocol V2 with metadata, and full observability history. Multi-chain EVM compatible: no fixed chainId, no fixed RPC, no hardcoded address, no owner/admin. Deploys unchanged on any EVM network.

Generates MultiSendExecutorV5 � production settlement and autonomous routing layer: full V4 feature set + settlement engine (PENDING ? LOCKED ? SETTLED / released), autonomous route optimizer with bridge health scoring, adapter health monitoring, failover system, gas payment model (native + token), partial batch execution, advanced EIP-712 with deadline+nonce, and complete timeline tracking. Multi-chain EVM compatible: no fixed chainId, no fixed RPC, no hardcoded address, no owner/admin.

Generates MultiSendExecutorV6 � autonomous intent network: full V5 feature set + relayer network (permissionless), intent marketplace (OPEN ? CLAIMED ? EXECUTING ? COMPLETED), auction execution model, reputation system, decentralized route selection with scoring, cross-chain receiver network with heartbeat, advanced intent security (expiration, invalidation, EIP-712 v2), atomic multi-chain execution, and protocol analytics. Multi-chain EVM compatible.

Generates MultiSendExecutorV7 � decentralized protocol layer with economic security: full V6 feature set + relayer staking + execution bonds + reward engine + decentralized fee market V2 + intent priority system + fraud protection (challenges) + cross-chain proof verification + batch intent execution + advanced network metrics. Multi-chain EVM compatible.

The currently generated contract is compiled in the browser via solc (loaded on demand) and deployed using the connected wallet (MetaMask / injected EVM). Nothing is simulated: the bytecode comes from the source shown above and the transaction is signed by your wallet on the selected network.

Sends the generated Solidity source to the Anthropic API for a structured security audit. Detects reentrancy, access-control flaws, integer overflows, uninitialized storage, gas inefficiencies, and more. A security score (0–100) is computed from the findings.

Interact with any deployed contract. Load the ABI from the last compiled contract or paste a custom one, enter the contract address, and call any function directly from your connected wallet.

All deployments are stored locally in your browser. Click any address to open it in the block explorer, or load its ABI directly into the Playground.

Estimates the gas cost of deploying the current contract before sending any transaction. Pulls live eth_gasPrice and eth_estimateGas from the selected network. USD price is fetched from CoinGecko.

Submits the flattened source code and ABI to the block explorer's verification API (Etherscan-compatible). After verification, anyone can read and interact with the contract on the explorer.

Share the current contract configuration as a URL or export deployment artifacts for use in Hardhat, Foundry, or CI pipelines.

Answer a few questions and ContractForge builds the right contract for you — no need to know which section to use.

Describe your contract in plain English. The Anthropic API writes production-ready Solidity for you — security-aware, gas-optimized, with NatSpec docs. You can then edit, audit, and deploy it directly.

Live on-chain analytics for deployed contracts. Pulls real transaction data via eth_getLogs and eth_getTransactionCount.

Automatically generates a comprehensive test suite for the current contract using the Anthropic API. Covers happy paths, edge cases, access control, and reentrancy. Download as .t.sol (Foundry) or .test.js (Hardhat).

Deploy a factory contract that creates ERC-20 tokens on demand. Each call to createToken() deploys a new token and registers it on-chain.

Multi-signature wallet requiring M-of-N owner confirmations before executing any transaction. Supports ETH and arbitrary contract calls.

On-chain governance with token-weighted voting. Create proposals, vote, and execute actions when quorum is reached.

Stake ERC-20 tokens and earn rewards over time. Configurable reward rate, lock period, and separate reward token support.

Automatically split incoming ETH and ERC-20 payments among multiple recipients based on predefined shares.

Decentralized marketplace with built-in escrow. Buyers deposit tokens, sellers deliver, and funds are released upon approval. Includes dispute resolution and deadline-based refunds.

Launch a token with liquidity and vesting in one flow. Creates an ERC-20 token with optional AMM pool and team vesting.

Deploy the same contract to multiple EVM networks in a single session. Use a contract generated in ContractForge or import an existing one with its ABI and bytecode.

Generate a Merkle tree airdrop contract. Paste a list of recipients (address,amount per line). The contract lets users claim their allocation with a proof.

Monitor deployed contracts for events. Add a contract address and watch for Transfer, Swap, Deposit, and other events in real time (polls every 30s).

Analyzes the current contract for gas optimization opportunities using AI. Suggests storage layout improvements, loop optimizations, and redundant operation removal.

Save, organize, and restore complete contract configurations. Export projects as .contractforge files to share or backup.

Browse all available contract templates organized by category. Click any template to start building.

Overview of all deployments with filtering and pre-deploy safety checks.

Automated regression tests. Generates and compiles each contract template to verify no generator is broken. Loads the Solidity compiler on demand.

Organize projects into teams. Create groups, associate projects, and manage your workspace.

Save snapshots of your contract at any point. Compare versions and restore previous states.

Structured pre-deploy security checklist powered by AI. Checks reentrancy, access control, integer safety, gas patterns, and best practices.

Generate CI/CD deployment configuration for your contract. Supports GitHub Actions, Foundry, and Hardhat.

Unified registry of all deployed contracts. Search, filter, and manage your deployments across all networks.

Advanced technical view. Inspect bytecode, ABI, compiler settings, and deployment data.

Your wallet-linked profile, preferences, and usage overview.

Browse, search, and use contract templates. Publish your own templates for the community.

Timeline of all actions: deploys, project saves, version snapshots, and more.
