lib.rs

1//! Reth's transaction pool implementation.
2//!
3//! This crate provides a generic transaction pool implementation.
4//!
5//! ## Functionality
6//!
7//! The transaction pool is responsible for
8//!
9//!    - recording incoming transactions
10//!    - providing existing transactions
11//!    - ordering and providing the best transactions for block production
12//!    - monitoring memory footprint and enforce pool size limits
13//!    - storing blob data for transactions in a separate blobstore on insertion
14//!
15//! ## Transaction Flow: From Network/RPC to Pool
16//!
17//! Transactions enter the pool through two main paths:
18//!
19//! ### 1. Network Path (P2P)
20//!
21//! ```text
22//! Network Peer
23//!     ↓
24//! Transactions or NewPooledTransactionHashes message
25//!     ↓
26//! TransactionsManager (crates/net/network/src/transactions/mod.rs)
27//!     │
28//!     ├─→ For Transactions message:
29//!     │   ├─→ Validates message format
30//!     │   ├─→ Checks if transaction already known
31//!     │   ├─→ Marks peer as having seen the transaction
32//!     │   └─→ Queues for import
33//!     │
34//!     └─→ For NewPooledTransactionHashes message:
35//!         ├─→ Filters out already known transactions
36//!         ├─→ Queues unknown hashes for fetching
37//!         ├─→ Sends GetPooledTransactions request
38//!         ├─→ Receives PooledTransactions response
39//!         └─→ Queues fetched transactions for import
40//!             ↓
41//! pool.add_external_transactions() [Origin: External]
42//!     ↓
43//! Transaction Validation & Pool Addition
44//! ```
45//!
46//! ### 2. RPC Path (Local submission)
47//!
48//! ```text
49//! eth_sendRawTransaction RPC call
50//!     ├─→ Decodes raw bytes
51//!     └─→ Recovers sender
52//!         ↓
53//! pool.add_transaction() [Origin: Local]
54//!     ↓
55//! Transaction Validation & Pool Addition
56//! ```
57//!
58//! ### Transaction Origins
59//!
60//! - **Local**: Transactions submitted via RPC (trusted, may have different fee requirements)
61//! - **External**: Transactions from network peers (untrusted, subject to stricter validation)
62//! - **Private**: Local transactions that should not be propagated to the network
63//!
64//! ## Validation Process
65//!
66//! ### Stateless Checks
67//!
68//! Ethereum transactions undergo several stateless checks:
69//!
70//! - **Transaction Type**: Fork-dependent support (Legacy always, EIP-2930/1559/4844/7702 need
71//!   activation)
72//! - **Size**: Input data ≤ 128KB (default)
73//! - **Gas**: Limit ≤ block gas limit
74//! - **Fees**: Priority fee ≤ max fee; local tx fee cap; external minimum priority fee
75//! - **Chain ID**: Must match current chain
76//! - **Intrinsic Gas**: Sufficient for data and access lists
77//! - **Blobs** (EIP-4844): Valid count, KZG proofs
78//!
79//! ### Stateful Checks
80//!
81//! 1. **Sender**: No bytecode (unless EIP-7702 delegated in Prague)
82//! 2. **Nonce**: ≥ account nonce
83//! 3. **Balance**: Covers value + (`gas_limit` × `max_fee_per_gas`)
84//!
85//! ### Common Errors
86//!
87//! - [`NonceNotConsistent`](reth_primitives_traits::transaction::error::InvalidTransactionError::NonceNotConsistent): Nonce too low
88//! - [`InsufficientFunds`](reth_primitives_traits::transaction::error::InvalidTransactionError::InsufficientFunds): Insufficient balance
89//! - [`ExceedsGasLimit`](crate::error::InvalidPoolTransactionError::ExceedsGasLimit): Gas limit too
90//!   high
91//! - [`SignerAccountHasBytecode`](reth_primitives_traits::transaction::error::InvalidTransactionError::SignerAccountHasBytecode): EOA has code
92//! - [`Underpriced`](crate::error::InvalidPoolTransactionError::Underpriced): Fee too low
93//! - [`ReplacementUnderpriced`](crate::error::PoolErrorKind::ReplacementUnderpriced): Replacement
94//!   transaction fee too low
95//! - Blob errors:
96//!   - [`MissingEip4844BlobSidecar`](crate::error::Eip4844PoolTransactionError::MissingEip4844BlobSidecar): Missing sidecar
97//!   - [`InvalidEip4844Blob`](crate::error::Eip4844PoolTransactionError::InvalidEip4844Blob):
98//!     Invalid blob proofs
99//!   - [`NoEip4844Blobs`](crate::error::Eip4844PoolTransactionError::NoEip4844Blobs): EIP-4844
100//!     transaction without blobs
101//!   - [`TooManyEip4844Blobs`](crate::error::Eip4844PoolTransactionError::TooManyEip4844Blobs): Too
102//!     many blobs
103//!
104//! ## Subpool Design
105//!
106//! The pool maintains four distinct subpools, each serving a specific purpose
107//!
108//! ### Subpools
109//!
110//! 1. **Pending**: Ready for inclusion (no gaps, sufficient balance/fees)
111//! 2. **Queued**: Future transactions (nonce gaps or insufficient balance)
112//! 3. **`BaseFee`**: Valid but below current base fee
113//! 4. **Blob**: EIP-4844 transactions not pending due to insufficient base fee or blob fee
114//!
115//! ### State Transitions
116//!
117//! Transactions move between subpools based on state changes:
118//!
119//! ```text
120//! Queued ─────────→ BaseFee/Blob ────────→ Pending
121//!   ↑                      ↑                       │
122//!   │                      │                       │
123//!   └────────────────────┴─────────────────────┘
124//!         (demotions due to state changes)
125//! ```
126//!
127//! **Promotions**: Nonce gaps filled, balance/fee improvements
128//! **Demotions**: Nonce gaps created, balance/fee degradation
129//!
130//! ## Pool Maintenance
131//!
132//! 1. **Block Updates**: Removes mined txs, updates accounts/fees, triggers movements
133//! 2. **Size Enforcement**: Discards worst transactions when limits exceeded
134//! 3. **Propagation**: External (always), Local (configurable), Private (never)
135//!
136//! ## Assumptions
137//!
138//! ### Transaction type
139//!
140//! The pool expects certain ethereum related information from the generic transaction type of the
141//! pool ([`PoolTransaction`]), this includes gas price, base fee (EIP-1559 transactions), nonce
142//! etc. It makes no assumptions about the encoding format, but the transaction type must report its
143//! size so pool size limits (memory) can be enforced.
144//!
145//! ### Transaction ordering
146//!
147//! The pending pool contains transactions that can be mined on the current state.
148//! The order in which they're returned are determined by a `Priority` value returned by the
149//! `TransactionOrdering` type this pool is configured with.
150//!
151//! This is only used in the _pending_ pool to yield the best transactions for block production. The
152//! _base pool_ is ordered by base fee, and the _queued pool_ by current distance.
153//!
154//! ### Validation
155//!
156//! The pool itself does not validate incoming transactions, instead this should be provided by
157//! implementing `TransactionsValidator`. Only transactions that the validator returns as valid are
158//! included in the pool. It is assumed that transaction that are in the pool are either valid on
159//! the current state or could become valid after certain state changes. Transactions that can never
160//! become valid (e.g. nonce lower than current on chain nonce) will never be added to the pool and
161//! instead are discarded right away.
162//!
163//! ### State Changes
164//!
165//! New blocks trigger pool updates via changesets (see Pool Maintenance).
166//!
167//! ## Implementation details
168//!
169//! The `TransactionPool` trait exposes all externally used functionality of the pool, such as
170//! inserting, querying specific transactions by hash or retrieving the best transactions.
171//! In addition, it enables the registration of event listeners that are notified of state changes.
172//! Events are communicated via channels.
173//!
174//! ### Architecture
175//!
176//! The final `TransactionPool` is made up of two layers:
177//!
178//! The lowest layer is the actual pool implementations that manages (validated) transactions:
179//! [`TxPool`](crate::pool::txpool::TxPool). This is contained in a higher level pool type that
180//! guards the low level pool and handles additional listeners or metrics: [`PoolInner`].
181//!
182//! The transaction pool will be used by separate consumers (RPC, P2P), to make sharing easier, the
183//! [`Pool`] type is just an `Arc` wrapper around `PoolInner`. This is the usable type that provides
184//! the `TransactionPool` interface.
185//!
186//!
187//! ## Blob Transactions
188//!
189//! Blob transaction can be quite large hence they are stored in a separate blobstore. The pool is
190//! responsible for inserting blob data for new transactions into the blobstore.
191//! See also [`ValidTransaction`](validate::ValidTransaction)
192//!
193//!
194//! ## Examples
195//!
196//! Listen for new transactions and print them:

224//!   });
225//!
226//!   // do something useful with the pool, like RPC integration
227//!
