Quick Reference

Types

Type	Description
`Euint128`	Handle to encrypted unsigned 128-bit integer
`Ebool`	Handle to encrypted boolean

Input Functions

Function	Description
`new_euint128`	Create encrypted u128 from ciphertext
`new_ebool`	Create encrypted bool from ciphertext
`as_euint128`	Convert plaintext u128 to encrypted handle
`as_ebool`	Convert plaintext bool to encrypted handle

Operations

Function	Description
`e_add`	Addition
`e_sub`	Subtraction
`e_mul`	Multiplication
`e_rem`	Remainder
`e_ge`, `e_gt`, `e_le`, `e_lt`, `e_eq`	Comparisons
`e_and`, `e_or`, `e_not`, `e_shl`, `e_shr`	Bitwise
`e_rand`	Random number generation
`e_select`	Conditional selection

Access Control

Function	Description
`allow`	Grant/revoke decryption access
`is_allowed`	Check decryption permission
`is_validsignature`	Verify attestation signatures

Every operation that produces a new handle requires calling allow() to grant decryption access. Use the remaining_accounts pattern to pass allowance PDAs and grant access in the same transaction. See Access Control for simulation patterns.

Account Structs

Struct	Used For
`Operation`	All encrypted operations
`Allow`	Granting/revoking access
`IsAllowed`	Checking permissions
`VerifySignature`	Attestation verification
