What it can do
| Tool | What it says it does |
|---|---|
address_tool | Work with public crypto addresses: op=detect (every chain/format an address fits; forks share version bytes, so expect several, e.g. a D... address returns doge, dgb and pivx; detect/validate support does not mean SwapChan can scan or sweep that chain), validate (address + chain), convert (address… |
airdrop_check | Unclaimed rewards and claimables for a wallet: Merkl incentive rewards on 9 EVM chains, legacy contracts (PoWH3D, Fomo3D, EtherDelta, Liquity surplus, and the LegacyETH registry: confirmed EtherDelta-style DEXes, Fomo3D forks, PoWH3D/Hourglass clones, old ETH wrappers, ICO/presale refunds… |
best_time_to_swap | Gas history for an EVM chain: base fee now vs the last ~1024 blocks (p10/median/p90 + series), a cheap/normal/expensive signal, and the historically cheapest hour (UTC) from SwapChan's own 10-minute gas samples (accumulating since deploy; historyDays says how much). Then offer the user a SwapChan… |
bolt11_decode | Decode a PUBLIC BOLT11 Lightning invoice (lnbc…): bech32 (BIP173) + tagged fields + the payee pubkey RECOVERED from the signature. Returns network, currency, timestamp, recovered_payee, amount_msat/amount_raw, payment_hash, description(_hash), payment_secret, payee_pubkey, features, fallback… |
bridge_doctor | Diagnose a bridge/cross-chain transfer by source tx hash: checks LI.FI, Across (needs fromChainId), Relay, deBridge DLN and THORChain in parallel, plus the origin receipt, and returns status (done/pending/failed/refunded/not_found), destination tx and what to do next. Then offer the user a… |
broadcast_tx | Relay a transaction the user's wallet already signed, unchanged, to 51 chains. SwapChan never signs, never holds keys and cannot alter signed bytes; it only relays. 51 chains. EVM (23): Ethereum, Base, Arbitrum One, OP Mainnet, Polygon PoS, BNB Smart Chain, Avalanche C-Chain, Linea, Scroll, zkSync… |
build_limit_order | Build a gasless CoW Protocol limit order (sell an ERC-20 for at least a target amount, valid until expiry). Returns EIP-712 typed data for the user's wallet to sign, the ERC-20 approve tx for CoW's vault relayer if the allowance is short, the current market amount for reference, and how to submit… |
build_plan_tx | Resolve a declarative blocktools Plan (JSON text) against a Context (JSON text: evm nonce, gas, max_fee_per_gas, priority_fee; utxo fee_rate) to UNSIGNED bytes: evm returns unsigned_tx (EIP-1559 hex), utxo returns a psbt with fee, vsize and outputs. The account family is not built here… |
build_revoke_tx | Unsigned transaction that sets an ERC-20 allowance to 0 (approve(spender, 0)) on an EVM chain. The user's wallet signs and sends it; SwapChan never signs. Use after check_approvals. Result includes `display` markdown with chan images: show it to the user. How to combine this with the other tools… |
build_send_tx | Build an UNSIGNED transfer of a token or the native coin to any recipient — e.g. "send 50 USDC to alice.eth" or "send 0.01 BTC to bc1q…". Resolves names (ENS/Basenames) and the token's decimals, constructs the transaction with blocktools, and re-checks the recipient with verifyTx so it can't pay… |
build_swap_link | Build a SwapChan deep link that opens swapchan.com with the swap card prefilled and auto-quoted, plus a permanent, unguessable short link (swapchan.com/s/<id>, random id, swap links do not expire). Accepts chain names or ids, token symbols or addresses, a decimal amount or "max" (needs owner)… |
build_swap_tx | Build the UNSIGNED transaction for the best (or chosen) route, plus any ERC-20 approval needed first and an eth_call simulation when an RPC is configured. Never signs, never holds keys or funds, never asks for keys: hand the result to the user's wallet (broadcast_tx can then relay the signed bytes… |
bytecode_inspect | Classify contract runtime code (eth_getCode hex): EIP-1167 minimal proxy + implementation, EIP-7702 delegation + delegate, EOF, size vs the EIP-170 24576-byte limit, code keccak-256, Solidity metadata (compiler, IPFS hash), notable opcode counts, and heuristic function-selector candidates. Pure… |
cancel_limit_order | Get the EIP-712 OrderCancellations typed data to cancel a CoW limit order off-chain (gasless). The owner signs it; POST {chainId, orderUids:[uid], signature} to /limit/cancel on the SwapChan API. Never signs. How to combine this with the other tools: swapchan_playbook (workflows: find-money… |
chain_params | Chain parameter table (reference data only; a listed chain is not a signing or recovery claim): 80 chains; Base58 version bytes, bech32 HRP and WIF byte for the 34 Bitcoin-family ones, checksum/SLIP-44/tx format for all. chain=<ticker> for one, omit for all. Pure, offline computation (blocktools)… |
check_approvals | List live ERC-20 allowances an EVM wallet has granted, on one EVM chain. Sources: GoPlus approval index (all chains) + full Approval-log history on Ethereum/Avalanche (Routescan); every allowance is re-checked on-chain. Flags unlimited, malicious, EOA or unknown spenders and ranks by risk. Each… |
check_watches | Check every watched token now: current price, % change since added, which thresholds triggered, and better-route alerts for watched swaps. Each item has a swapUrl. When something triggered, tell the user and offer the SwapChan swap (take profit to USDC, buy the dip, or the better route). Then… |
combine_psbts | Merge cosigners' partially signed PSBTs (base64 or hex) for the same transaction and finalize once the threshold is met. Returns signed_tx (hex of the finalized tx, ready for the user's own broadcast) and psbt (base64 of the combined PSBT). Errors: no_psbts, not_a_psbt, psbts_do_not_combine… |
compare_routes | Compare every route SwapChan found, ranked best-first by net USD received, across aggregators and bridges. Pass extra destination chains in alsoToChainIds to compare same-chain vs cross-chain outcomes side by side. Swap-chan lines up the whole cast. Result includes `display` markdown with chan… |
contract_abi | Load an EVM contract's ABI like a block explorer's Contract tab: Sourcify first, then Etherscan (when configured), else pass abi. Follows EIP-1967 proxies (shows the implementation's functions, calls still go to the proxy). Returns read (view/pure) and write functions with signatures, selectors… |
contract_approve_call | Pre-signing verdict for one EVM contract call: builds the calldata, re-encodes it with the full ABI and exact signature, builds an unsigned tx (placeholder nonce and gas; the wallet sets the real ones), approves the calldata against the ABI (blocktools evmApproveCall: ok, unknown_selector or… |
contract_build_creation | Build an unsigned EVM contract creation from bytecode plus optional constructor ABI and args (blocktools buildEvmTransfer create). Returns the initcode (data, no 'to'), initcode_keccak256, an approval of the initcode against that hash or a createHash you pin (blocktools evmApproveCall), a verifyTx… |
contract_encode_call | Build the calldata for any function of an EVM contract (write functions included) and return it with the target, chain, value (payable functions only, in wei) and a decoded human-readable view, for the user's own wallet to review, sign and send. SwapChan never signs, sends or broadcasts it… |
contract_read | Call one view/pure function of an EVM contract via eth_call and return the ABI-decoded result. A failed or reverted read returns ok=false with an error code, never a zero. Read-only; nothing is signed or sent. Powered by blocktools (ABI coding). How to combine this with the other tools… |
contract_reader | Plain-English read of a token/contract: verified source (Sourcify, Routescan), proxy/upgradeability (EIP-1967 slots), owner and whether ownership is renounced, and the owner's dangerous powers found in the bytecode (mint, pause, blacklist, fee/tax setters, upgrade) with a risk level. Solana… |
create_address | Predict a contract's deployment address: deployer + nonce (CREATE), or deployer (factory) + 32-byte salt + init_code or init_code_hash (CREATE2, EIP-1014). Returns the EIP-55 address. Pure, offline computation (blocktools); nothing is fetched or stored. How to combine this with the other tools… |
evm_abi | Solidity ABI work on public data: op=encode (sig like transfer(address,uint256) + args as a JSON list → selector + calldata), decode (input hex + sig or abi → named args; with types like (uint256,address) decodes return data; output=true decodes a function's return data; reverts and panics are… |
explain_transaction | Plain-English explanation of any transaction on SwapChan's chains: EVM (decoded token transfers, approvals, method name, fee in USD, swap detection), Solana (signer's balance changes, programs like Jupiter/Raydium/Pump.fun), Bitcoin (inputs/outputs/fee rate) and Tron (TRX/TRC-20 transfers… |
find_money | HEADLINE TOOL. "Give me your wallet address and I'll find you money." Scans one wallet (address, ENS, Basename or SNS) and returns RANKED actions with estimated $ values: unclaimed rewards (Merkl), forgotten money in old contracts (PoWH3D/P3D dividends, Fomo3D vaults, EtherDelta balances, Liquity… |
find_money_batch | Paste a list of PUBLIC addresses (any mix: EVM 0x…, ENS/Basenames, .sol, Solana, Tron, Bitcoin; commas/newlines/whatever) and SwapChan auto-detects each chain (EVM addresses are scanned on every EVM chain) and runs find_money on all of them in the background. Returns a jobId immediately; poll… |
find_money_status | Poll a find_money_batch job: status (running/done), progress {done,total,percent}, running total, per-wallet results, ranked items, the verbatim 'summary' and the 'plan'. While running, wait pollAfterSeconds and call again; tell the user progress. When done, relay summary verbatim and walk plan… |
get_gas | Current network fees on all SwapChan chains: EVM gas price, Solana priority fee, Bitcoin sat/vB, Tron energy fee, each converted to the USD cost of a typical swap, plus the cheapest chain. Cached 15s. Pass history=<chain> for the last ~1024 blocks plus the historically cheapest hour. Use it to… |
get_quote | Get SwapChan's single best quote (most value landing in the wallet after gas and fees) for a same-chain or cross-chain swap. Read-only, no transaction. Swap-chan checks every counter so you don't have to. Result includes `display` markdown with chan images and a swapchan.com link: show it to the… |
get_route_status | Track a submitted swap or cross-chain transfer by source tx hash: pending, done, failed or not_found, plus the destination tx hash once it lands.
