Build a ready-to-sign SeaDrop mint transaction for an NFT collection across 13 chains, including Ethereum, Base, Optimism, Arbitrum, Polygon, Avalanche, BSC, Zora, Robinhood Chain and Arc. Takes a contract or OpenSea URL, the minting wallet and a quantity; returns to, data, value, chainId, gas limit and suggested fees. The caller signs with its own wallet - no key is ever handled. Refuses to build a transaction that would revert, and says why.

Allow-List Mint Builder
Allow-List Mint Builderallowlist-builder.vercel.app
Build a ready-to-sign SeaDrop allow-list (FCFS / whitelist) mint transaction across 13 chains. Give it your merkle proof and the stage parameters the project published; it recomputes your leaf and checks the proof against the drop's on-chain merkle root before building anything, trying every known leaf and pair-ordering convention. If the proof does not match it refuses and explains why, so you never burn gas on an InvalidProof revert. The caller signs with its own wallet.

Reads the deployed bytecode directly, resolving proxies so the implementation is scanned too, and reports whether ownership is renounced plus any missing standard ERC-20 functions. Works on 13 chains including Robinhood Chain and Arc. Facts only: no score, no verdict, no trading advice.
