Verify you are on real Animica mainnet, and which chain id to sign with. Animica answers that question with TWO numbers: the native chain is id 1, while the EVM compatibility facade reports 149 (eth_chainId 0x95, net_version "149"). A wallet porting Ethereum tooling signs with the wrong one. Returns both, the disagreement named, plus genesis hash, fork id, policy hash and the built-in consensus checkpoints a light client pins against. All read live. No model.

Animica · Qrng Draw
animica.dev
Random bytes from the Animica node's randomness service with a signed digest attestation and an entropy-health report, 1..1024 bytes per draw. Current trust model, stated up front and in every response: the entropy source is a software CSPRNG (os.urandom) and the signer is a software key, so source.is_quantum=false and attestation.attested=false today; those fields flip truthfully if a hardware/quantum provider is ever connected. The free catalog entry carries the same live entropy block, so you can check the source before paying.
