Movemate

A library of module building blocks for Move on Aptos and Sui.

Movemate provides an advanced standard library of common modules in the Move ecosystem (working in tandem with the native frameworks), focusing on security, efficiency, composability, and ease of implementation.

Modules

• acl: Multi-role access control list (ACL).
• bcd: Binary canonical DEserialization. Convert vector<u8> to u64 and u128.
• bloom_filter: Space-efficient probabilistic data structure for checking if an element is part of a set.
• box: On Aptos, send objects without the recipient having to set up a store for themselves beforehand. On Sui, transfer objects with the store ability but not the key ability.
• crit_bit: Crit-bit trees data structure. (Thanks to Econia.)
• date: Date conversion library in Move.
• escrow (Sui only): Very basic object escrow module on Sui.
• escrow_shared (Sui only): Basic object escrow module with refunds and arbitration on Sui.
• governance: On-chain coinholder governance (store coins and other objects; on Aptos, retrieve a signer for special actions like upgrading packages).
• i64: Signed 64-bit integers.
• i128: Signed 128-bit integers.
• linear_vesting: Linear vesting of coins for a given beneficiary.
• math: Standard math utilities missing in the Move language (for u64).
• math_safe_precise: mul_div for u64s while avoiding overflow and a more precise quadratic function.
• math_u128: Standard math utilities missing in the Move language (for u128).
• merkle_proof: Merkle proof verification utilities.
• pseudorandom: Pseudorandom number generator.
• to_string: u128 to String conversion utilities.
• u256: Unsigned 256-bit integer implementation in Move. (Thanks to Pontem.) Includes bitwise operations and vector<u8> conversion.
• vectors: Vector utilities--specifically, comparison operators and a binary search function.
• virtual_block: Replace latency auctions with gas auctions (with control over MEV rewards) via virtual blocks.

Outside the repo

• multisig_wallet: Multisignature wallet for coins and arbitrary objects.
• oracle_factory (Sui only): Create and share custom oracles, aggregating data across validator sets.
• xyk_amm: Constant product (XY=K) AMM (like Uniswap V2).
