Building Apps on Twin.fun

Use the bonding curve contract and subgraph to build dashboards, bots, and custom experiences.

Read-Only Integrations

• Surface prices, candles, trades, and holders from the subgraph.
• Display supply, last trade price, estimated slippage, and fees.

Access Control

• Verify key ownership by reading sharesBalance[id][user] on-chain or consuming the Holder entity from the subgraph.
• Gate features based on balance thresholds (commonly ≥1 key).

Event-Driven UIs

• Subscribe to the Trade event to update prices, holders, and activity feeds in real time.
• Combine event streams with subgraph polling for resilient UX.

Security Checklist

• Display fee and value breakdowns before executing buys.
• Warn users that buyShares requires the exact msg.value.
• Handle chain reorgs by waiting for confirmations on critical UX state.
