This doc lists all the data Peggy module reads/writes to its state as KV pairs
Params is a module-wide configuration structure that stores parameters and defines overall functioning of the peggy module. Detailed specification for each parameter can be found in the .

Stores Delegate Ethereum address

's account address
[]byte{0x1} + []byte(validatorAddr)

common.Address
Protobuf encoded
Stores Validator
account address indexed by the Delegate Ethereum address
[]byte{0xfb} + []byte(ethAddress)
Validator address
sdk.ValAddress
Protobuf encoded
When a validator would like to delegate their voting power to another key. The value is stored using the orchestrator address as the key
[]byte{0xe8} + []byte(AccAddress)
Orchestrator address assigned by a validator
[]byte
Protobuf encoded
This is the validator set of the bridge. Created automatically by Peggy module
during EndBlocker.
Stored in two possible ways, first with a height and second without (unsafe). Unsafe is used for testing and export and import of state.
[]byte{0x2} + nonce (big endian encoded)
Validator set
types.Valset
Protobuf encoded
The latest validator set slash nonce. This is used to track which validator set needs to be slashed and which already has been.
[]byte{0xf5}
Nonce
uint64
encoded via big endian
Nonce of the latest validator set. Updated on each new validator set.
[]byte{0xf6}

Validator Batch Confirmation
types.MsgConfirmBatch
Protobuf encoded
User withdrawals are pooled together in Peggy Tx Pool
ready to be batched later by a Batch Creator
.
Each withdrawal is indexed by a unique nonce set by the Peggy module
when the withdrawal was received.
[]byte{0x7} + []byte("lastTxPoolId")
nonce of outgoing withdrawal
uint64
Big endian encoded
Monotonically increasing value for each withdrawal received by Injective
[]byte{0x6} + []byte("lastTxPoolId")
Last used withdrawal ID
uint64
Big endian encoded
OutgoingTxBatch
represents a collection of withdrawals of the same token type. Created on every successful MsgRequestBatch
.
[]byte{0xa} + []byte(tokenContract) + nonce (big endian encoded)
A batch of outgoing transactions
types.OutgoingTxBatch
Protobuf encoded
[]byte{0xb} + block (big endian encoded)
A batch of outgoing transactions
types.OutgoingTxBatch
Protobuf encoded
Monotonically increasing value for each batch created on Injective by some Batch Creator
[]byte{0x7} + []byte("lastBatchId")
Last used batch ID
uint64
Big endian encoded
Represents the latest slashed block height. There is always only a singe value stored.
[]byte{0xf7}
Latest height a batch slashing occurred
uint64
Big endian encoded
Represents the latest bloch height at which a Validator
started unbonding from the Validator Set
. Used to determine slashing conditions.
[]byte{0xf8}
Latest height at which a Validator started unbonding
uint64
Big endian encoded
A denom that is originally from a counter chain will be from a contract. The token contract and denom are stored in two ways. First, the denom is used as the key and the value is the token contract. Second, the contract is used as the key, the value is the denom the token contract represents.
[]byte{0xf3} + []byte(denom)
Token contract address
[]byte
stored in byte format
[]byte{0xf4} + []byte(tokenContract)
Token denom

This entry represents the last observed Valset that was successfully relayed to Ethereum. Updates after an attestation of ValsetUpdatedEvent
has been processed on Injective.
[]byte{0xfa}
Last observed Valset on Ethereum
types.Valset
Protobuf encoded
The nonce of the last observed event on Ethereum. This is set when TryAttestation()
is called. There is always only a single value held in this store.
[]byte{0xf2}
Last observed event nonce
uint64
Big endian encoded
This block height of the last observed event on Ethereum. There will always only be a single value stored in this store.
[]byte{0xf9}
Last observed Ethereum Height
uint64
Protobuf encoded
This is the last observed event on Ethereum from a particular Validator
. Updated every time the asssociated Orchestrator
sends an event claim.
[]byte{0xf1} + []byte(validator address)
Last observed event by some Validator
types.LastClaimEvent
Protobuf encoded
Attestation is an aggregate of claims that eventually becomes observed by all orchestrators as more votes (claims) are coming in. Once observed the claim's particular logic gets executed.
Each attestation is bound to a unique event nonce (generated by Peggy contract
) and they must be processed in order. This is a correctness issue, if relaying out of order transaction replay attacks become possible.
[]byte{0x5} + event nonce (big endian encoded) + []byte(claimHash)
Attestation of occurred events/claims
types.Attestation
Protobuf encoded
A computed hash indicating that a validator set/token batch in fact existed on Injective. This checkpoint also exists in Peggy contract
. Updated on each new valset update and token batch creation.
[]byte{0x1b}
Last created checkpoint hash on Injective
gethcommon.Hash
store in byte format
A list of known malicious Ethereum addresses that are prevented from using the bridge.
[]byte{0x1c} + []byte(ethereum address)
Empty []byte slice
gethcommon.Hash

confirmation for a particular token batch. See
Stored in two possible ways, first with a height and second without (unsafe). Unsafe is used for testing and export and import of state. Currently is hardcoded to only accept batches with a single token type and only pay rewards in that same token type.
