Estamora Documentation

Estamora is a policy-guarded payments and milestone escrow protocol built on Stellar (Soroban).

It provides trust-minimized multi-party escrow, autonomous agent spend limits, and pre-flight transaction simulation to protect merchants, buyers, and automated workflows from failures, fraud, and budget overruns.

The Problems Estamora Solves

Unprotected Commerce & High-Risk Agreements
Traditional transfers on Stellar finalize irreversibly in 3–5 seconds. If a merchant fails to fulfill goods or services, the buyer has zero on-chain recourse. Estamora provides progressive milestone release, automated timeout refunds, and mediator arbitration.
Unbounded Agent Spends & Rogue Workflows
Autonomous AI agents and automated services need delegated allowances, but granting full private key access risks catastrophic fund loss. Estamora introduces on-chain 24-hour rolling spend caps and per-call limits.
Silent Failures & Blind Submissions
Transactions submitted with insufficient allowances, expired timeouts, or invalid state waste fees and fail silently. The @estamora/sdk engine simulates every call before wallet signing, scoring risk and explaining exact contract error codes.
