Lock ETH or USDG behind a password-protected URL. The recipient unlocks from any wallet — no recipient address required at send time.

[02] Philosophy

CLAIMA turns a transfer into controlled access: the sender locks ETH or USDG in a claim vault, sets a password, and shares a link that can be opened without choosing the receiver wallet up front.

A claim link proves intent, not identity. The link carries the path to the locked value while the secret gates the release.

[04] Locking

Claimable Transfers

CLAIMA locks value in a Robinhood Chain vault instead of sending it directly to a wallet. The sender creates a password-protected claim link, and the receiver unlocks the funds only when the secret matches the on-chain hash.

[05] Disclosure

Privacy by Intent

CLAIMA does not promise invisible money; it removes the direct recipient handoff. Amounts and claims remain on-chain, while access is gated by the secret — value moves through a shareable link without exposing a fixed destination wallet up front.

[06] How it works

One claim link.
Every locked transfer.

Whether you are locking funds, sharing a password link, or letting a receiver claim from a vault, CLAIMA turns the flow into one clean intent. No fixed recipient wallet at send time. No complex escrow UX. Just controlled access.

01

Vault

Locks ETH or USDG inside a single-use burner vault.

02

Link

Turns access into a shareable claim URL with a client-side secret.

03

Secret

Hashes passwords before validation so claims depend on proof.

04

Claim

Releases funds to whoever proves the secret from the claim flow.

05

Reclaim

Lets senders recover expired or unclaimed value in future flows.

06

Audit

Keeps transparent on-chain state without choosing a recipient up front.
