What Sigma is

Sigma is a financial operating system for the on-chain economy that automates crypto accounting and tracks treasury activity. It matches on-chain transactions to ledger entries in real time, categorizes transactions as they arrive, and records each token's fiat value using its price at the time of the transaction. Wallets can be linked with read-only access, and wallet imports are supported. Sigma consolidates chains and entities into one ledger and describes coverage across 31 chains, including every major EVM chain. Its treasury monitoring tracks holdings, yields, runway, and wallet movements in real time. For invoice workflows, Sigma offers matching with Vision AI. Reconciled books can be synced to QuickBooks, Xero, or NetSuite, and accounting exports are supported. Sigma identifies finance teams, accountants, and auditors as users it serves. A free plan is available, while paid pricing is on request. Sales inquiries can be sent to [email protected].
