Multisig account transactions involve complex threshold matching across signers and operations. Stellar Expert's tx-signers-inspector library automatically discovers eligible signers, calculates required thresholds, and detects excessive signatures—turning manual verification into a few API calls.
Multisig is a foundational security pattern on Stellar—accounts can have multiple signers with different weights, and transactions require discrete thresholds to execute. But verifying whether a transaction will pass multisig validation is complex: you need to know which signers are eligible, whether their combined weight meets the operation threshold, and whether extra signatures might cause rejection. Stellar Expert built tx-signers-inspector, a JavaScript library that answers these questions automatically. It inspects a transaction, discovers all potential signers, suggests the minimal signing set, and checks feasibility for a given signer group. The tool handles multi-operation transactions, future account changes, and custom Horizon endpoints, removing guesswork from multisig workflows.
