Solana developer tools
Small, fast utilities that answer one question each. Everything runs client-side; RPC calls go straight from your browser to the endpoint you choose.
Paste "custom program error: 0x1771" or any Solana error and get the program, variant, cause and fix.
Paste a signature and see every instruction, account, log line and the exact reason a transaction failed.
Derive program derived addresses from seeds with typed inputs. Shows the bump and the exact bytes used.
Paste a mint address and see its extensions, authorities and transfer fees in plain language with risk flags.
Rent-exempt minimum for any account size, with presets for token accounts, mints and Anchor accounts.
Compute unit limit × micro-lamport price = total fee. Understand what you actually pay per transaction.
Convert between lamports and SOL instantly, with the math shown.
Check whether a string is a valid Solana address, whether it is on the ed25519 curve, and what lives there on-chain.
