Build a ready-to-sign token transfer across 13 chains, including Robinhood Chain and Arc. Send an ERC-20 by contract address, or native currency with token set to native. Returns to, data, value, chainId, gas limit and suggested fees. Flags low balance, unpayable gas and contract recipients before you sign. The caller signs with its own wallet: no key is ever handled.

SeaDrop Mint Reader
SeaDrop Mint Readerseadrop-reader.vercel.app
Read the live SeaDrop mint configuration for an NFT collection across 13 chains, including Ethereum, Base, Optimism, Arbitrum, Polygon, Avalanche, BSC, Zora, and the newer Robinhood Chain and Arc. Accepts a contract address or an OpenSea item URL. Returns mint price, stage start and end, max per wallet, fee recipient and creator payout, and whether the stage is public or gated by an allow list, signed mint or token gate. Read-only: holds no keys.

NFT Mint Transaction Builder
NFT Mint Transaction Buildermint-builder-three.vercel.app
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.

Token Owner Powers Scan
Token Owner Powers Scantoken-scanner-nine.vercel.app
Scan an ERC-20 and report what powers its owner still holds: mint new supply, pause transfers, blacklist wallets, change fees or limits, or upgrade the contract. 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.

Token Approval Checker and Revoke Builder
Token Approval Checker and Revoke Builderapproval-checker-nine.vercel.app
Find out which contracts can spend a wallet's ERC-20 tokens, and get ready-to-sign transactions to revoke them. Scans the Approval log history where the node allows it, and always checks well-known spenders such as Permit2, Seaport and the major routers, plus any you supply. Flags unlimited allowances and ones larger than the balance. Works on 13 chains including Robinhood Chain and Arc. The caller signs: no key is ever handled.

Jwt Decode
Jwt Decodex402.bankr.bot
Decodes a JWT and inspects its claims without needing the signing key. Base64URL-decodes header and payload, parses standard claims (iss, aud, sub, exp, iat, nbf, jti), and reports algorithm, key id (kid), token type (typ), TTL, and clock-validity (is_expired / is_not_yet_valid / is_currently_valid_by_clock). Does NOT verify signatures — for inspection only, never trust output for auth decisions. Use it as a JWT parser, JSON Web Token inspector, Bearer token debugger, OAuth ID-token reader, or Auth0 + Cognito + Firebase token inspector.
