Support the work
Donate
RabbitSoftware is independent research tooling. Donations are voluntary gifts toward its running costs, such as hosting and development. They are not investments, they buy no goods or services, and they are not tax-deductible unless this page says so.
Addresses
Send Bitcoin only to the Bitcoin address, and ETH only on Ethereum mainnet to the Ethereum address. Tokens or coins sent on other networks, or to the wrong address, can be lost for good. Blockchain transactions cannot be reversed. For a first donation, send a small test amount, and check the first and last six characters of the address in your wallet against this page.
Check that these addresses are ours
Both addresses come from one key that lives inside a Google Cloud hardware security module (HSM). Its private key cannot be exported or read by anyone. To prove control, that key signed this message:
RabbitOS donation wallet proof of control, 2026-10-15
Ethereum signature (paste the address, message and signature into any Ethereum “verify message” tool, for example the one on Etherscan):
0x93ad45bbd3ca37c4b540f86e85e5a9d6db350e274bc338a4fb0a83e58551e734096c58b61cdb10a48e8a284776337ac2c9a775680536aa4ab173ac9345c01ada1c
The same public key (compressed, hex) gives both addresses: 03db772bb7f8987bb8315c0d09eb23c30ba2ce33e760c9d74695903fb4061300f8. The full public record is in wallet.json.
Our public chains are also anchored to Bitcoin through OpenTimestamps. The proofs are listed in the anchor index and can be checked with the standard ots verify tool. An anchor proves that a document existed by a given Bitcoin block; it does not prove the document is true.
