how parlayz works.

custodial in name only. you control your phantom or backpack; we just manage an in-app balance for fast bet placement.

on first connect, the server mints a deterministic deposit keypair tied to your wallet, encrypted at rest with an aes-256 secret. you deposit sol to that address — credited to your in-app balance once confirmed on chain. every bet is a database write against that balance; no signature needed per wager.

withdrawals are server-signed transfers back to the wallet you connected. you remain the only owner of your phantom seed phrase. parlayz never sees it.

• phantom / backpack via @solana/wallet-adapter
• sign-in with solana (siws) for session — no email, no kyc
• deposit address shown on /wallet, settles on-chain
• withdrawals: <2s after click. server signs the transfer.

every leg multiplies. one settles wrong and the ticket dies. that is the entire point.

what's unusual about parlayz: a leg can be a world cup moneyline (sports), an anytime-scorer prop (sports), a champions league spread (sports), and a $wif closes-higher-today (pumpfun) — on the same ticket.

odds multiply: 1.85 × 2.10 × 2.40 × 1.95 = 18.18×. stake 0.50 sol → potential 9.09 sol.

• min 2 legs, max 10 legs per ticket
• no correlated legs (e.g. same-game ml + ml)
• each leg settles independently; payout only when all hit
• single-game parlays use uncorrelated lines (ml + total + scorer)

markets close at kickoff (sports) or end of day utc (pumpfun close-higher) or fixed timestamp (futures).

after the result is final on the source feed, the resolver settles every position in the same transaction and credits winners.

resolution feeds: api-football for goals & match results, the-odds-api for cross-checking, dexscreener (with a 60-second twap) for pumpfun close prices. ambiguous results void the leg and refund pro-rata.

• sports: settled within 5 minutes of match end
• pumpfun close-higher: settled at 00:00 utc
• voids return stake to balance; parlay continues with adjusted odds
• all settlements logged on /portfolio with a bytes-on-disk audit trail

every market carries a published vig. we never adjust odds against a specific user. we never delay a bet to fade a hot streak.

for sports markets, displayed odds are the consensus median across our bookmaker feed minus ~3–5% margin.

for pumpfun synthetic markets, the vig is exactly 5% baked into every outcome symmetrically — so the book has positive expected value on every wager, but the bettor still pockets the full multiplier when their pick lands.

• sports vig: ~3–5% (sourced from regulated eu/uk books)
• pumpfun vig: exactly 5% — symmetric, published, never hidden
• no per-user odds adjustments. no delayed placement.
• rng-driven markets (none in v1) would publish their seed.

every fixture, every price, every player stat is pulled from a live api. no mock data. when an api key is absent the page renders an empty state with setup instructions — never a fake number.

• the-odds-api — wc 2026 fixtures + h2h/spread/totals + outrights
• api-football — club fixtures, group standings, live scores
• football-data.org — current-season top scorers (pl, la liga, ucl)
• dexscreener — pumpfun trending coins, mcap, volume, liquidity
• coingecko — sol spot price for ui conversions
