This method is currently only supported for these smart contract addresses: 0x69007702764179f14F51cdce752f4f775d74E139, 0x00000000000002377B26b1EdA7b0BC371C60DD4f, 0xd6CEDDe84be40893d153Be9d467CD6aD37875b28, 0x63c0c19a282a1B52b07dD5a65b58948A07DAE32B, and 0x77021100bD87b7008E5E1989d0eB38555d0d0000.

Idempotency on errors: On 4xx or 5xx, Privy caches the response and replays it for the same key. Generate a new key to retry after a server error. Policy violations are an exception and allow same-key retries.
