# Hybrid Proof Types

Hybrid proofs embed verified `ETH_BLOCK_HEADER_DATA` (14 fields, \~540 bytes) directly instead of full consensus-layer proofs. The verifier trusts this data because the local prover already verified it (hybrid mode = same process). These proofs are significantly smaller than their full counterparts.

## EthHybridAccountProof

Hybrid account proof: MPT proof + verified header data (stateRoot from header\_data)

The Type is defined in [src/chains/eth/ssz/verify\_proof\_types.h](https://github.com/corpus-core/colibri-stateless/blob/v1.1.26/src/chains/eth/ssz/verify_proof_types.h#L722).

```python
class EthHybridAccountProof(Container):
    accountProof : List [bytes_1024, 256]
    address      : Address
    storageProof : List [EthStorageProof, 256]
    header_data  : EthBlockHeaderData
```

## EthHybridCallProof

Hybrid call proof: accounts + verified header data (stateRoot, feeRecipient, etc.)

The Type is defined in [src/chains/eth/ssz/verify\_proof\_types.h](https://github.com/corpus-core/colibri-stateless/blob/v1.1.26/src/chains/eth/ssz/verify_proof_types.h#L730).

    header_data      : EthBlockHeaderData
```

## EthHybridReceiptProof

Hybrid receipt proof: raw tx + SSZ Merkle proof for tx + Patricia proof for receipt + header\_data

The Type is defined in [src/chains/eth/ssz/verify\_proof\_types.h](https://github.com/corpus-core/colibri-stateless/blob/v1.1.26/src/chains/eth/ssz/verify_proof_types.h#L744).
