The Trust Layer for Digital Assets
Create, sign and publicly verify agreements, crypto payments and digital proofs.
ProofLayer does not have access to private keys or funds. All signatures are cryptographic proofs of wallet control, not transaction authorizations.
Build trust into your product
ProofLayer provides APIs for agreements, receipts, invoices, wallet verification and public cryptographic proofs — without handling private keys or wallet complexity.
Create via API
Generate agreements, receipts, invoices and digital proofs from your backend.
Collect signatures
Use hosted wallet-native signing flows without wallet complexity.
Verify anywhere
Public verification links, embedded verification and API endpoints.
Crypto payments & receipts
Create crypto payment buttons or connect your existing checkout infrastructure.
Automatically generate verifiable receipts and invoice-ready payment records from real on-chain transactions.
From backend to signed proofs, verified payments and public verification links in seconds.
Built for modern crypto operations
Wallet signatures
Users sign directly with their wallet. No accounts, emails or identity friction.
Public verification layer
Every agreement, payment and proof is publicly verifiable via URL or API.
Non-custodial infrastructure
Your wallets. Your funds. Your infrastructure. ProofLayer never controls private keys, assets or transactions.
API-first integration
Use ProofLayer directly or integrate verification into exchanges, payment systems and digital platforms.
Create, sign and verify digital proofs
Generate agreements, invoices, receipts and cryptographic proofs with instant public verification, wallet-native signatures and verifiable on-chain evidence.
Create agreements & digital proofs
Create verifiable agreements, invoices, receipts, treasury records and digital proofs. Generate documents manually or automate them directly from your backend using the ProofLayer API.
Cryptographic signing & PDF generation
Sign agreements using Bitcoin or EVM wallets and generate verifiable PDFs with QR codes, hashes and public validation links.
Public verification
