# Bounded Onchain

> Add onchain to a Bounded app: Solana collections, embedded non-custodial wallets for email/social users (@user.address, Turnkey by default), client- and server-signed transactions, DEX/perps trading patterns, and crypto payments (accept USDC/crypto non-custodially). Use for wallet, token, on-chain transaction, or crypto payment work. Part of the Bounded skill family; policy and the actor model live in bounded-backend.

# Bounded onchain

Wallets, tokens, on-chain transactions, and payments. The **canonical Bounded
email/social login includes a wallet by default**: keep the default Turnkey auth
and supported email/social logins carry a real `@user.address` - see
[docs/embedded-wallets.md](docs/embedded-wallets.md). `@user.id` (the account id)
stays the identity/ownership key; `@user.address` is the wallet. On-chain writes
still pass their policy rules and invariants first, so pair this with the
**bounded-backend** skill for the governing rules. To route across the family, see
the root **bounded** skill.

## Rules Of Thumb

- **Default onchain login = default Turnkey email/social auth, plus optional wallet login.** Do not add `authMode` or `auth.wallets` for the normal path; supported email/social users already have `@user.address`. Deploy `"auth": { "wallets": true }` only for an EXTERNAL-keypair session (wallet login, a server-SDK keypair client, the CLI keypair data lane). Full rule and the opt-outs: [docs/embedded-wallets.md -> recommended login](docs/embedded-wallets.md#the-recommended-login-for-an-onchain-app).
- Use `@user.address` only for wallet/onchain semantics; use `@user.id` for normal ownership. See the bounded-backend skill.
- **A guest (`signInAnonymously`) session can never write an `onchain: true` collection, on ANY network.** Poofnet, devnet, and mainnet all return `403 anonymous_onchain_blocked` before a transaction is built, so a guest flow that works against a test network cannot break on promotion. Keep the guest-reachable surface offchain and prompt the upgrade before the first onchain write. See [guests cannot write to an onchain collection](docs/onchain.md#guests-cannot-write-to-an-onchain-collection).
- **When a function's existing manifest description accepts account IDs**, a non-pubkey string resolves to its own program-signed PDA. `@contract.address` is ONE shared fund for the whole app; a named id is a separate fund per name. Do not assume every source, owner, creator, or destination accepts all three custody forms - check that argument's manifest description on the function page. When separate pots of user money coexist (escrows, auctions, prize pools, per-tenant balances), use named accounts where accepted. Decide before the first deposit; retrofitting means migrating live balances.
- For onchain writes, use explicit network/RPC configuration and devnet by default; do not treat immediate read-after-write as confirmation.
  The CLI submits the transaction itself, and it reads its endpoint ONLY from `SOLANA_DEVNET_RPC_URL` / `SOLANA_MAINNET_RPC_URL`: no flag, no config-file setting, and no public-RPC fallback.
  An unset variable fails the write before signing with `validate pre-built transaction: SOLANA_DEVNET_RPC_URL is required ...`, so set it in the shell running `bounded` whenever an app is `realtime_devnet` or `realtime_mainnet`.
  See [CLI submission needs an explicit RPC endpoint](docs/onchain-troubleshooting.md#cli-submission-needs-an-explicit-rpc-endpoint).
- Mainnet is a real target, not a placeholder: the program is live on mainnet-beta. Creating a mainnet app requires a paid account plan (no API key or shared secret), and an app **you** create is owned on-chain by the creator's wallet **immutably** - a wallet your signed-in identity can prove it controls: the local CLI keypair, or on a web login your Bounded account's own wallet, whose permit signatures happen through a per-deploy browser approval. It can never be ownership-transferred. (oApp roots and workloads are also mainnet, but the platform mints them under a Bounded-custodied owner; you never create those yourself - see the **oapps-fun** skill.) See [docs/onchain.md](docs/onchain.md).
- `@contract.address` is the Solana program-ID sentinel, not the app escrow address returned by a direct query.
  Supported built-in plugins resolve the sentinel to the app escrow PDA.
  On the current deployed Devnet runtime, do not compose the sentinel as `@AccountPlugin.getAccountAddress(@contract.address)`: that call fails because the sentinel is address-typed while this function currently accepts a string account id.
  For a Devnet policy query that needs the concrete escrow address, bind the current Devnet program ID as a string literal: `@AccountPlugin.getAccountAddress("openTv7fbpYSseNHYmCZFZ1CZgj4r8D9fKNgEz1qo6F")`.
  This literal is Devnet-specific and must be updated if the deployed program changes.
  See [policy-primitives.md](docs/policy-primitives.md#contractaddress-is-a-sentinel-not-the-escrow-address).
- Treat discovery, deployed-runtime support, and live-network verification as three independent states.
- Use `bounded plugins list --json` and `bounded plugins describe <plugin.function> --json` as the offline callable signature source before authoring a hook.
- Run `bounded verify --protocol <protocol> --json` on the actual policy and inspect advisory `capabilityReadiness`, while still requiring retained live evidence before claiming network support.
- Check the [Solana devnet capability catalog](docs/solana-capability-status.md) before proposing any plugin or primitive.
- Never infer devnet support from a compiler tag, manifest, proof contract, Poofnet model, lookup-table entry, or local validator test.
- When live evidence uses a hosted release marker, resolve its environment-qualified site URL from `bounded domains list --app-id <id> --env <environment> --json` `slugUrl` or the exact successful site-deploy receipt `url`.
  Require the JSON field itself for staging evidence instead of copying a human-rendered hostname.
  `bounded apps inspect` proves the active policy/runtime publication and carries no hosted URL.
- Never emit runtime-v2 primitives for a runtime-v1 deployment; follow [docs/policy-primitives.md](docs/policy-primitives.md).
- Current chain-backed named queries belong on `onchain: true` paths. Anonymous execution is admitted for identity-independent queries whose path read rule authorizes the caller; a query reading `@user.address`/`@user.evmAddress` requires that identity. The anonymous surface is the browser SDK, not the CLI.
- Do not recommend an `onchain: false` view for an offchain-only plugin read until standalone chain-query execution is fixed.
- Treat runtime-v3 governance the same way: enroll only after the deployed capability registry reports v3, and publish governance from observed chain state rather than policy intent.
- Keep Poofnet and Solana behavior paired.
- Use `bounded wallet fund` only for explicit development funding on `realtime_offchain`.
  The caller must be the app owner, an admin, or a developer, and the balance exists only inside the selected app's simulated ledger.
- Pure/read primitives must return the same shape in runtimes where they are actually executable, and mutating primitives must apply a modeled effect or fail closed.
- Validation-only success is a parity bug.
- For a Poofnet onchain hook, application-side success means `_hook_completed == _transaction_hash`. Row existence and `_error_message == null` are only pending state. But those stamps are SIMULATOR-only: a policy RULE that requires them is permanently unsatisfiable on a real-chain protocol - a payout gated that way becomes a one-way valve that locks user funds, and every sim-side proof and test stays green. Rules gate on a declared field the hook itself writes (`paidAt`-style) or on the hook-derived head state; reserved `_` stamps are for Poofnet clients only. Give every semantic operation id a policy-legal failed-attempt retry path. See [reserved receipt stamps are Poofnet-only](docs/policy-native-state-machines.md#reserved-receipt-stamps-are-poofnet-only-never-read-them-in-a-rule).
- Helius mirroring is environment-level Bounded infrastructure: one raw program webhook per environment/network, never one per app. App builders never create webhook URLs or supply provider secrets, and the operator runbook (webhook, secrets, queue/DLQ, recovery) lives in the monorepo, not this skill. See [mirror completeness](docs/onchain.md#mirror-completeness) for the app-facing caveats.
- Crypto is accepted non-custodially; sellers settle to their own wallet.
