Problem
New players need MON for gas before they can use any onchain features (match recording, identity registration, wagers). This is friction — someone has to manually send them MON.
Proposal
Sponsor gas for core match operations so players never need to think about gas money. Only wagers (where real MON is at stake) should require the player to hold MON.
What should be gas-free for players
- Match result signing — already free (off-chain EIP-712)
- Match recording — already free (arena submits via
_try_record_match())
- Identity registration — could be arena-sponsored (arena calls
register() on behalf of player)
- Elo posting — already free (arena posts)
- Prediction pool bets — could be relayed through arena
What should still cost the player gas
- Wager propose/accept — real money, player should hold their own MON
- Wager settle — could be sponsored since it's permissionless
Approaches
- Arena as relayer (simplest) — arena already submits most txs. Extend to cover identity registration and prediction bets. Players sign, arena relays.
- Monad paymaster (if available) — ERC-4337 or native account abstraction. Players sign UserOps, paymaster covers gas.
- Meta-transactions (ERC-2771) — contracts accept forwarded calls from a trusted forwarder. More contract changes.
Current state
The arena already sponsors match recording, pool creation/resolution, and Elo posting. The gap is identity registration and prediction pool bets — those still require the player to submit and pay gas.
Priority
Post-hackathon. Current flow works for the demo (we fund wallets manually). This becomes important when external players join and we can't hand-deliver MON to everyone.
