Support the tools

Everything I build is free and stays free: no paid tier, no licence key, nothing held back. It is a one-person workshop, so if something here has saved you an evening or a server, this page is how you can say so.

Several chains really do share one address. Ethereum, Base, Optimism and BNB Smart Chain are one account, because one key controls it on all of them. It looks like a mistake and it is not.

Only what is offered. A coin that has no tile here is not supported, and a chain that is not listed under the coin you picked cannot receive it. ETH on BNB Smart Chain is the trap worth naming: what trades there as ETH is a bridged token, not the real thing, and it is deliberately not offered.

None of this changes anything about the software. Everything stays free, with no paid tier and no licence key, whether anybody uses this page or not.
