[PR Checklist](#pr-checklist) + +--- + +## Summary + +Replaces every `env.events().publish((Symbol, ...), data)` call in the +Finchippay contract with a typed `#[contractevent]` struct, emitted via the +non-deprecated `env.events().publish_event(&event)`. Events are now +schema-enforced: the struct's snake-case name is the first topic and every +field is a named entry in the event data Map, so indexers and generated SDK +clients deserialize a stable, typed event instead of guessing at tuple layout. + +| Metric | Value | +| --------------------------------------------------- | ----------------------------- | +| Typed `#[contractevent]` structs added | **53** | +| `publish()` โ†’ `publish_event()` call sites migrated | **60** | +| Contract modules touched | **7** + new `events` module | +| `#[allow(deprecated)]` removed | โœ… (impl block + test module) | +| Backend files updated | **4** | +| Test result | **185 passed, 0 failed** | + +--- + +## Problem Statement + +The contract emitted events through the low-level +`env.events().publish((Symbol, ...), data)` API, which the Soroban SDK (โ‰ฅ 22.0) +has deprecated. This caused five distinct problems: + +1. **Deprecation** โ€” `cargo check` produced **33 deprecation warnings**, and the + entire `FinchippayContract` impl block carried `#[allow(deprecated)]`. The + contract could not be upgraded past an SDK that removes `publish()`. +2. **Schema fragility** โ€” event payloads were raw tuples with _implicit_ types. + Adding/removing a field silently broke downstream indexers, dashboards, and + SDK consumers. (The `events.rs` catalog had already drifted from the actual + emitted names, e.g. the catalog said `tip_sent` / `escrow_created` while the + code emitted `tip` / `escrow_create`.) +3. **No type safety** โ€” a field-type mismatch compiled but emitted garbage. +4. **Missed SDK integration** โ€” Soroban RPC's `getEvents` topic filtering and + generated event listeners could not consume ad-hoc tuple events. +5. **Audit blocker** โ€” third-party auditors flag deprecated API usage as a + pre-mainnet concern. + +--- + +## Solution Overview + +```rust +// contracts/finchippay-contract/src/events.rs +#[contractevent] +#[derive(Clone, Debug)] +pub struct EscrowCreated { + pub escrow_id: u32, + pub from: Address, + pub to: Address, + pub amount: i128, + pub release_ledger: u32, +} +``` + +```rust +// contracts/finchippay-contract/src/escrow.rs โ€” before +env.events().publish( + (Symbol::new(&env, "escrow_create"), next_id), + (from.clone(), to.clone(), amount, release_ledger), +); + +// โ€” after +env.events().publish_event(&EscrowCreated { + escrow_id: next_id, + from: from.clone(), + to: to.clone(), + amount, + release_ledger, +}); +``` + +On-chain, the new event serializes as: + +- **topic** `["escrow_created"]` โ€” the struct's snake-case name (a `Symbol`). +- **data** `Map { "escrow_id": 0, "from": Gโ€ฆ, "to": Gโ€ฆ, "amount": "โ€ฆ", "release_ledger": โ€ฆ }` โ€” + a `SCV_MAP` keyed by field-name symbols. + +--- + +## Design Decisions + +### 1. `env.events().publish_event(&event)` rather than `event.publish(&env)` + +The issue specified `env.events().publish(&event_struct)`. The SDK's actual +non-deprecated method is `Events::publish_event(&impl Event)`; the bare +`publish` remains the deprecated two-argument tuple API. `publish_event` is +used consistently so every call site reads as a mechanical replacement of the +old `publish`. + +### 2. Default (`map`) data format + +Every struct uses the `#[contractevent]` default `data_format = "map"`, so +fields are emitted as a `SCV_MAP` keyed by field-name symbols. This is what the +issue asks for ("typed event structs with named fields") and lets the backend +parser address fields by name rather than by tuple position. + +### 3. Struct-name topics (intentional schema normalization) + +The first topic is the struct's snake-case name. This normalizes the handful of +ad-hoc legacy topic strings to the names already documented in `events.rs`: + +| Legacy topic | New topic (struct) | +| ------------------ | ---------------------------------------- | +| `tip` | `tip_sent` (`TipSent`) | +| `receipt` | `receipt_minted` (`ReceiptMinted`) | +| `escrow_create` | `escrow_created` (`EscrowCreated`) | +| `escrow_claim` | `escrow_claimed` (`EscrowClaimed`) | +| `stream_open` | `stream_opened` (`StreamOpened`) | +| `stream_claim` | `stream_claimed` (`StreamClaimed`) | +| `multisig_create` | `multisig_created` (`MultisigCreated`) | +| `multisig_approve` | `multisig_approved` (`MultisigApproved`) | + +All other event names are preserved verbatim. + +### 4. Backend parser decodes SCVal XDR + +`backend/src/services/eventParser.js` now decodes base64 `SCVal` XDR using +`@stellar/stellar-sdk`, converting addresses to StrKey (`Gโ€ฆ`/`Cโ€ฆ`) and integers +to precision-safe strings, then extracts `from`/`to`/`amount` from the named +data fields via an updated `EVENT_PARTICIPANT_MAP`. It also degrades gracefully +to already-decoded (plain-object) input for tests. + +### 5. `events.rs` module promoted into the crate + +`events.rs` previously existed as an orphan file (not declared in the module +tree). It is now `pub mod events;` in `lib.rs`, holding the typed structs +alongside the maintained catalog documentation. + +--- + +## Complete Event Migration Map + +### `lib.rs` โ€” admin, governance,

The +legacy `env.events().publish()` API is no longer used anywhere in the codebase, +and the `#[allow(deprecated)]` attribute has been removed from the contract +implementation block. -1. Replace all `env.events().publish(...)` calls with `#[contractevent]` - struct definitions and `env.events().publish(&event)` invocations. -2. Bump `STORAGE_LAYOUT_VERSION` and ensure the new event types are documented. -3. Update the event indexer (`backend/src/services/eventIndexer.js`) to parse - the new topic format (the `#[contractevent]` macro generates a 16-byte topic - hash from the struct name). -4. Re-deploy and verify with `soroban contract invoke --id -- events`. +- Typed event structs live in [`src/events.rs`](src/events.rs) and are emitted + via `env.events().publish_event(&Event { ... })`. +- The backend indexer (`backend/src/services/eventParser.js`) decodes the typed + event format (topic symbol + named data Map). +- Event field layout is schema-enforced by the SDK, so adding or removing a + field is a compile-time change rather than a silent indexer break. ### Tracking diff --git a/contracts/finchippay-contract/src/airdrop.rs b/contracts/finchippay-contract/src/airdrop.rs index 2ac0aee9..a580d15f 100644 --- a/contracts/finchippay-contract/src/airdrop.rs +++ b/contracts/finchippay-contract/src/airdrop.rs @@ -1,5 +1,6 @@ -use soroban_sdk::{contracttype, xdr::ToXdr, Address, Bytes, BytesN, Env, Symbol, Vec};
