  24. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/check_txSolana pre-sign transaction check: simulate an unsigned transaction on mainnet and catch drainers before signing. Run on every transaction before signing. Shows what each wallet gains and loses, blocks drainer tricks, and catches failures and expired blockhashes before you pay a fee. Decodes each step, dry-runs it on live mainnet, finds each wallet's SOL and token changes, and answers OK, REVIEW or BLOCK with reasons.$0.02 Solanano paywall2 payers0% up
  25. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/find_tokenFind the real Solana token address for a ticker or name, and spot copycat tokens using the same ticker. Run whenever a user names a token ("buy BONK"). Tickers aren't unique; copycats reuse them. Never take an address from memory. Finds the real address for a ticker or name, ranks matches by verification and liquidity, and warns when copycats share the ticker.$0.01 Solanano paywall2 payers0% up
  26. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/feeSolana priority fee estimate: cheap, normal and fast prices in micro-lamports per compute unit, and total in SOL. Run before setting a priority fee. Gives the price in the unit Compute Budget expects (micro-lamports per compute unit) and the total in SOL, so a unit mix-up never overpays. Turns what recent transactions paid for priority into three prices: cheap, normal, fast. Pass your transaction to get its compute limit and exact cost at each.$0.01 Solanano paywall2 payers0% up

  28. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/explain_txExplain a Solana transaction in plain words: what each wallet gained and lost, fee, programs, and why it failed. Run after a transaction lands or fails, to report what happened instead of guessing from logs. For failures it names the failing program and the fix. Reads a confirmed transaction: whether it worked, the fee, each wallet's SOL and token changes, the programs used, and why it failed.$0.01 Solanano paywall2 payers0% up
  29. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/convertConvert Solana token amounts between normal units and raw base units using the token's on-chain decimals. Run before putting any token amount in a transaction. "5 USDC" is 5,000,000 raw units; wrong decimals send 1,000x too much or too little. Converts between normal amounts and raw units with the token's real on-chain decimals.$0.01 Solanano paywall2 payers0% up

Run when a wallet was drained or money went missing, or before trusting an address someone gave you: follows the money and flags sweeper, pass-through and lookalike-address patterns. Follows a wallet's money through its recent transactions: net SOL and token change and the other side of each, where most money went, and drain patterns with evidence.$0.02 Solanano paywall2 payers0% up
  33. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/build_txBuild a Solana SOL or token transfer, or a Jupiter swap, as an unsigned transaction that is already safety-checked.

  35. 22solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/tx_matchesVerify a Solana transfer or swap does exactly what was asked (token, amount, recipient) before signing. Run just before signing a transfer built from a request like "send 5 USDC to X", or a swap built for "swap 1 USDC for JUP". Confirms it moves exactly that token, amount and recipient, nothing more, or that the swap sells exactly that amount and pays the bought token back to you.
