Two elliptic curve standards: - secp256k1 is used by Bitcoin and Ethereum - secp256r1, aka P-256, is used everywhere else. Passkeys, the Secure Enclave, iCloud Keychain, Yubikey, ... If you can verify P-256 signatures onchain, you can make a *much* nicer self-custody experience. Safe, fast, no seed phrase.

read this paper on ECC point multiplication opti for EVM. it reduces the P256 verification gas cost by a factor of 11x and perf by a factor of 6x https://eprint.iacr.org/2023/939.pdf
