Presign
A policy and simulation boundary for agent-originated on-chain writes that approves, routes, or blocks each action and preserves a signed decision receipt.
Agencies and professional operators can give an agent a tool that sends, swaps, stakes, or signs in minutes, but the wallet and policy controls around that action were not designed for delegated machine intent. Once an on-chain write executes, review is too late and reversal may be impossible. The opening is the final decision boundary before signing: simulate the actual call, test it against client authority, and bind the outcome to a reviewable receipt.
The agency, treasury, or automation owner deploying agents that can initiate on-chain writes for clients but cannot justify enterprise-wallet policy pricing or client-by-client custom controls.
The product preserves fast agent execution while making irreversible writes conditional on explicit authority and predicted consequences.
A shared policy and receipt layer can govern recurring actions across clients through software.
Multiple cross-references and inbound connections support the direction, while the stored score remains moderate.
Agent-facing on-chain write tools now exist, while policy, simulation, and approval remain separate components; the product converts that trust gap into a sharp pre-sign mechanism.
Three of five assumed interfaces remain unverified, convergence is moderate, and wallet or custody incumbents already own adjacent policy and signing controls.
