Implementation Design

Smart contract architecture of Axiom Protocol

Contract	Function
XRPVault (future stable vaults)	Staking, share accounting, reward distribution
EligibilityRegistry	Snapshot and percentile tracking
FeeRouter	Routing staker fees and yield flows
MarketFactory (upgradeable)	Market creation and implementation deployment
AxiomConditionalTokens	ERC-1155 positions, split, merge, redeem
AxiomCTFMarket	Per-market condition wrapper and resolution oracle
AxiomCTFExchange	Onchain CLOB settlement for matched trades
AxiomRewards	Onchain claims for epoch-based rewards

Upgradeable Market Factory: UUPS proxy pattern to evolve implementation registration and deployment logic over time. Upgrade control transitions from launch administration to more decentralized governance over time.

Upgrade admin staged transition:

1. Dev EOA (Phase 1)

2. 3-of-5 multisig (Phase 2)

3. Governance-controlled timelock and multisig (Phase 3)
