The organiser sets it up
Add the model clause to the agreement, enter the parties and their accounts, and load the final PDF. The app produces the signature-block text and a signing link.
Agreement Signer
Sign agreements with your wallet. Prove it on a public ledger.
Each party signs the final PDF with its own HSuite Wallet. The signature is recorded on Hedera or the XRP Ledger, and anyone can verify — at any time, without us — that every party signed exactly that document.
A signature that belongs to the signer
Many “blockchain signing” services sign on your behalf and only anchor a hash. Here the party’s own wallet signs a readable statement: its legal name, the agreement title, the PDF fingerprint, an express acceptance and the time.
That statement and its signature are written to a public ledger by the signer’s account. Nothing depends on our servers — there are none. The PDF never leaves your computer.

How it works
Three steps, all in the browser. A few minutes per party.
2 · Sign
Each party signs
Open the link, connect HSuite Wallet, check the PDF and approve two requests: the signature and its recording on the ledger. The network fee is under one US cent.
3 · Verify
Anyone can check
The verification page re-reads the public ledger and re-checks every signature. Download one signed PDF: the agreement followed by an execution certificate, with the evidence attached.
What makes it different
- Self-custody. The signer’s own key signs. We never see keys, funds or documents.
- No server, no account. The app runs entirely in your browser; drafts stay in it.
- Verifiable without us. Evidence lives on Hedera or the XRP Ledger, where anyone can re-check it. It stays there even if this site disappears.
- Built around a contract clause. A model clause (English and Portuguese) makes wallet signatures the agreed way of signing, with network time prevailing and a hash alone never counting as execution.
- Evidence you can file. A single signed PDF with an execution certificate and the full evidence embedded inside it.
- Two networks. Hedera (Hedera Consensus Service) and the XRP Ledger, with testnets for rehearsal.
Who it is for
Web3-native organisations
Already operating on-chain
DAOs, funds, treasuries and ecosystem companies whose authorised signers already act through wallets, directly or through a custodian.
Cross-border deals
Parties in different countries
One neutral, public record that every side can verify independently, instead of trusting a single provider’s database.
Know the limits
Not for every document
It is not a qualified e-signature, a notary or a registry, and some documents require a special legal form. Read the disclaimer and involve your lawyer.
Agreement Signer is software provided by Strater Global LLC; it is not legal advice and Strater Global is not a party to agreements signed with it. Legal effect depends on the governing law and on the parties’ agreement — see the disclaimer and the model clause. HSuite Wallet is provided by HSuite.
