The migration will be bound to this exact block hash, not only the block number. The project declares the recovery point and policy. IceRoot does not decide which historical state to recover.

Project-declared migration policy

A versioned policy from the fixed menu: a declared recovery point, excluded addresses, and the treatment of escrow and contract holdings.

Policy from the fixed menu

Declared Exclusion Policy v1

Exclude the project-declared exploit address

Explicitly declared for this demo policy.

Inspect policy identifier and exclusions

Policy hash · Fixture: 0x93ad4f7cbb198f2a67e0d956bf803aacd20ed3fbc8a217950e25d6a73bcf1402
Excluded source address: 0x5555666677778888999900001111222233334444

Contract and escrow holdings stay unissued unless their controller binds them before certification; the declared policy covers the rest. IceRoot does not adjudicate economic ownership.

Supply reconciliation

Reconciled

Every difference is accounted for, separately from the reconstructed source state.

Included in the listUnissued or excluded

Source reported supply: 500,000,000 NST
Reconstructed balances: 500,000,000 NST
Unexplained difference: 0 NST
Contract holdings · unissued unless bound: − 31,000,000 NST
Excluded by policy: − 3,500,000 NST
Migration supply: 465,500,000 NST

3,500,000 NST excluded by the project-declared address exclusion. 31,000,000 NST in 299 contract and system accounts stays unissued unless bound before certification. No unexplained difference. 31,281 source holders; 30,981 included; 1 excluded by policy.

Special addresses

Proposed handling is a review aid. The contract-holding rule and the declared policy determine inclusion.

Source address	Type	Balance	% supply	Policy result
`0x00000…dead`	Burn address	4,200,000 NST	0.84%	Unissued unless bound before certification
`0x22223…1111`	Uniswap V2 pool	8,450,221 NST	1.69%	Unissued unless bound before certification
`0x33334…2222`	Staking contract	12,100,000 NST	2.42%	Unissued unless bound before certification
`0x44445…3333`	Bridge escrow	5,000,000 NST	1.00%	Unissued unless bound before certification

Inspect address evidence and full identifiers

Burn address

0x000000000000000000000000000000000000dead

Demo evidence: the address matches the declared burn-address entry in the fixture. This label is not a decision about ownership.

Unissued unless its controller binds it before certification, under every policy. This is the protocol's contract-holding rule, not a policy choice.

Liquidity pool

0x2222333344445555666677778888999900001111

Demo evidence: the fixture classifies this address as a pool contract. No liquidity-provider ownership has been reconstructed or assigned.

Unissued unless its controller binds it before certification, under every policy. No liquidity-provider ownership is reconstructed or assigned.

Staking contract

0x3333444455556666777788889999000011112222

Demo evidence: the fixture classifies this address as a staking contract. No depositor balances, claims or destination owners are inferred.

Unissued unless its controller binds it before certification, under every policy. Depositor balances are not looked through.

Bridge escrow

0x4444555566667777888899990000111122223333

Demo evidence: the fixture marks this address as a bridge escrow. Cross-network claims, liabilities and controllers have not been determined.

Unissued unless its controller binds it before certification, under every policy. The interface does not redistribute escrowed balances.

Each certifying validator rebuilds the list from the declared source checkpoint and policy. They do not simply sign a file uploaded by the project.

Transparent inputs. A clear boundary.

This public preview contains fixture data. Certification demonstrates the intended verification experience; it does not approve a rollback, establish rightful ownership, or perform a migration.
