Bridge Events
The polygon.bridge_events table provides indexed views of all bridge transactions from or to a specified chain, and includes the other chain involved. All bridge events tables follow the same database schema presented below.
Columns
| Name | Type | Description |
|---|---|---|
| block_number | integer |
The block number at which the event occurred. |
| bridge_name | text |
The name of the bridge protocol that facilitated the event. |
| contract_address | text |
The contract address where tokens were deposited to. |
| contract_version | text |
The version of the bridge contract interacted with (e.g. v1 or v2). |
| direction | text |
The direction of the bridge events with respect to the chain being queried (e.g. 'IN' or 'OUT'). |
| from_address | text |
The address that sent tokens on the from_chain_id (null if not found). |
| from_chain_id | text |
The name of the from chain (e.g. 'ETHEREUM', 'SOLANA', 'AVALANCHE'). |
| from_quantity | numeric |
The quantity of the from_token_address. |
| from_token_address | text |
The token address deposited on the from_chain_id (null if not found). |
| from_transaction_hash | text |
The transaction hash on the from_chain_id in which tokens were bridged out of. |
| log_index | integer |
The log index at which the event occurred. |
| metadata | jsonb |
Protocol-specific metadata for the event (e.g. txn ID that links txns on each chain). |
| timestamp | timestamp without time zone |
The timestamp at which the event occurred. |
| to_address | text |
The address that received tokens on the to_chain_id (null if not found). |
| to_chain_id | text |
The name of the to chain (e.g. 'ETHEREUM', 'SOLANA', 'AVALANCHE'). |
| to_quantity | numeric |
The quantity of the to_token_address. |
| to_token_address | text |
The token address unlocked on the to_chain_id (null if not found). |
| to_transaction_hash | text |
The transaction hash on the to_chain_id in which tokens were bridged into. |
| transaction_hash | text |
The transaction hash at which the event occurred. |
| __block_number | integer |
The last block number in the batch that the data was updated in. |
| __confirmed | boolean |
Flag indicating whether the transfer has been confirmed. |
