ATSHI is the only L1 to natively support six elliptic-curve and lattice schemes — Ed25519, X25519, secp256k1, BLS12-381, NIST P-256/P-384, and post-quantum Falcon-512. Pick the right algorithm per transaction.
Hardware compatible. FIPS compliant. Quantum ready.
Most blockchains hard-code one curve forever — locking in their threat model. On ATSHI, the curve is a transaction field. A wallet can pay with Ed25519, sign a multisig with BLS12-381, and prepare a high-value transfer with Falcon-512 — in the same block.
A complete cryptographic palette — pre-quantum performance and post-quantum security in the same protocol.
Fast, simple, deterministic. The modern standard for digital signatures — used by SSH, GPG, libsodium. Default for ATSHI wallet signing operations.
Diffie-Hellman key agreement on Curve25519. Used to derive shared secrets for end-to-end encrypted messaging, FHE key derivation, and TLS handshakes.
The Bitcoin & Ethereum curve. Native support enables seamless bridges, identity migration, and signature verification of external chain transactions.
Pairing-friendly curve for short signatures, signature aggregation, and threshold cryptography. Powers ARCH consensus and multi-validator attestations.
NIST-standard curves used by government, healthcare, and finance. FIPS 140-2/3 compliance. HSM and Smart Card hardware support out of the box.
NIST post-quantum signature standard. Lattice-based, resistant to Shor’s algorithm. Use for long-term sealed transactions, regulatory archives, and quantum-grade wallets.
Switch schemes per transaction — no protocol fork required. Adapt to new threats, new standards, new hardware as they emerge.
Falcon-512 protects against quantum computing attacks. Long-term assets stay sealed even when Shor’s algorithm becomes practical.
Compatible with existing security hardware — HSM, YubiKey, Ledger, Smart Cards. No vendor lock-in, no special drivers.
FIPS 140-2/3 with P-256 and P-384. Suite B compatible for government workloads. eIDAS-ready signatures for European compliance.
secp256k1 means direct bridges to Bitcoin and Ethereum without wrapping or proxies. Cross-chain identity becomes a primitive.
BLS12-381 enables thousands of attestations to be combined into one signature. ARCH consensus uses this to scale validator participation.

From everyday payments to quantum-resistant vaults — every transaction can pick its own mathematical foundation. No forks, no migrations, no compromise.
