Actual signing happens in the caller's code.\n\n## Instruction Building with `accountsStrict`\n\n```typescript\nconst ix = await program.methods\n .buy(amount, maxSolCost, flags)\n .accountsStrict({\n global: GLOBAL_PDA,\n bondingCurve: bondingCurvePda(mint),\n user: userPublicKey,\n // ... all required accounts\n })\n .remainingAccounts(additionalAccounts)\n .instruction();\n```\n\n## PDA Derivation\n\n```typescript\nconst [pda, bump] = PublicKey.findProgramAddressSync(\n [Buffer.from(\"bonding-curve\"), mint.toBuffer()],\n PUMP_PROGRAM_ID\n);\n```\n\n## RPC Batching\n\n```typescript\nconst accounts = await connection.getMultipleAccountsInfo([\n bondingCurvePda(mint),\n GLOBAL_PDA,\n FEE_CONFIG_PDA,\n]);\n```\n\n## Token-2022 Support\n\nThe SDK supports both SPL Token and Token-2022:\n- `createV2Instruction` creates Token-2022 mints\n- `tokenProgram` parameter selects the appropriate program\n- Associated Token Accounts (ATAs) are created idempotently\n\n## Account Decoding\n\n```typescript\nconst bondingCurve = program.coder.accounts.decode('bondingCurve', accountInfo.data);\n```\n\nNullable variants handle missing accounts:\n```typescript\nconst bc = decodeBondingCurveNullable(accountInfo); // returns null instead of throwing\n```\n\n## Transaction Simulation\n\n```typescript\nconst result = await connection.simulateTransaction(tx, [signer]);\n// Parse return data from simulation logs\n```\n\n## BN.js Arithmetic\n\nAll amounts use `BN` for arbitrary-precision integer arithmetic:\n\n```typescript\nconst fee = amount.mul(new BN(feeBps)).div(new BN(10000));\nconst ceilFee = amount.mul(new BN(feeBps)).add(new BN(9999)).div(new BN(10000));\n```\n\n## Patterns to Follow\n\n- Always use `accountsStrict` — not `accounts` — for type-safe account specification\n- Use `getMultipleAccountsInfo` to batch account fetches\n- Build instruction arrays, not transactions — let callers compose\n- Handle both Token and Token-2022 programs via parameter\n- Use nullable decoders for optional accounts\n\n## Common Pitfalls\n\n- `AnchorProvider` with dummy wallet is for instruction building only — never sign with it\n- `getMultipleAccountsInfo` returns nulls for missing accounts — always check\n- Transaction size limit is 1232 bytes — large instruction sets may need multiple transactions\n- `remainingAccounts` order matters — the on-chain program reads them positionally\n\n"
