Bitcoin Core already implements this safety limit with the "absurd fee" limit of 10000 * the minimum relay fee. This limit is active in both the wallet and the sendrawtransaction RPC call. Additionally for the wallet there is a user configurable -maxtxfee option to limit fees set by the wallet which currently defaults to 0.1 BTC. --=20 https://petertodd.org 'peter'[:-1]@petertodd.org 0000000000000000024eabe5049843ea6d73558e960d6bcead9e91a24cab1161 --6TrnltStXW4iwmi0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- iQGrBAEBCACVBQJW2FgfXhSAAAAAABUAQGJsb2NraGFzaEBiaXRjb2luLm9yZzAw MDAwMDAwMDAwMDAwMDAwMjRlYWJlNTA0OTg0M2VhNmQ3MzU1OGU5NjBkNmJjZWFk OWU5MWEyNGNhYjExNjEvFIAAAAAAFQARcGthLWFkZHJlc3NAZ251cGcub3JncGV0 ZUBwZXRlcnRvZC5vcmcACgkQJIFAPaXwkftiCAf/VtwM2Lykzc7lco5qpO9+NfkD ld7zq5YDgppi1V7tQB2U0EGnTpHMIP3FXaf3PUqAb4T0u4c+quv0s0TBQwmm5HTD xqU/VGTBzJrEQrAA5TVkZ+Ei0OXoB95IG1f0v6ycijo5uB2dDhwQPUaG533wAjFG QR83HJky/4nbwznmFbGt6YSYPRgF7NEalX3RKq031r9fyJD5cz1UJrZhCx8kACJ7 k8/qtX7YnlEd8uujvLl+DFyBfFQQu2jhqwaBoEBPIFhZaAIMLzqw/VxQkIc+zMsh yyJ77Q+IOsQ6E+0A6aogtrE9LLdmbSMQbUirrzkjU9qv0OGkO+XTZpvwnxHDvw== =jGtw -----END PGP SIGNATURE----- --6TrnltStXW4iwmi0--
