CSEarlyAdoption
CSEarlyAdoption.sol is the supplementary contract responsible for the Early Adoption members' verification. It validates if the address is eligible to create a Node Operator during the Early Adoption period or if the address is eligible to create a Node Operator with the discounted bond curve once the Early Adoption period is over. It stores information about eligible addresses that have already been used to create a Node Operator.
Upgradability
The contract is immutable.
State Variables
TREE_ROOT
Root of the EA members Merkle Tree
bytes32 public immutable TREE_ROOT;
CURVE_ID
Id of the bond curve to be assigned for the EA members
uint256 public immutable CURVE_ID;
MODULE
Address of the Staking Module using Early Adoption contract
address public immutable MODULE;
Functions
consume
Validate EA eligibility proof and mark it as consumed
Called only by the module
function consume(address member, bytes32[] calldata proof) external;
Parameters
| Name | Type | Description |
|---|---|---|
member | address | Address to be verified alongside the proof |
proof | bytes32[] | Merkle proof of EA eligibility |
isConsumed
Check if the address has already consumed EA access
function isConsumed(address member) external view returns (bool);
Parameters
| Name | Type | Description |
|---|---|---|
member | address | Address to check |
Returns
| Name | Type | Description |
|---|---|---|
<none> | bool | Consumed flag |
verifyProof
Check is the address is eligible to consume EA access
function verifyProof(address member, bytes32[] calldata proof) public view returns (bool);
Parameters
| Name | Type | Description |
|---|---|---|
member | address | Address to check |
proof | bytes32[] | Merkle proof of EA eligibility |
Returns
| Name | Type | Description |
|---|---|---|
<none> | bool | Boolean flag if the proof is valid or not |
hashLeaf
Get a hash of a leaf in EA Merkle tree
Double hash the leaf to prevent second preimage attacks
function hashLeaf(address member) public pure returns (bytes32);
Parameters
| Name | Type | Description |
|---|---|---|
member | address | EA member address |
Returns
| Name | Type | Description |
|---|---|---|
