Custody Agreement

Who holds the keys

High-value works are held in a 2-of-3 multisig vault. No single party can move an artwork alone, and the platform does not hold more than one key.

• Artist key — held by the artist[0xArtist — to be configured]
• Platform key — held by Dimension[0xPlatform — to be configured]
• Arbitrator key — held by an independent third party[0xArbitrator — to be configured]

Any transfer out of the vault requires 2 of 3 signatures and a 48-hour timelock.

What the platform does not do

• The platform does not hold the only key and cannot move an artwork unilaterally.
• The platform does not custody proceeds; settlement happens on-chain through the auction contract.
• The platform is not an insurer; insurance, where offered, is a separate agreement with a licensed provider.

Insurance

Qualifying high-value sales (at or above the published threshold) carry an insurance & custody fee that is included in the purchase price. The fee funds a dual-track cover: an on-chain smart-contract policy and a traditional fine-art policy. Placing a bid or completing a purchase constitutes your acknowledgment of this arrangement.

• Who is covered — the buyer/collector of the covered artwork is the beneficiary of the cover while the work is held in custody or escrow. The platform is the policyholder on the traditional policy where required by the provider.
• What is covered — loss caused by a compromised or lost custody signer key, smart-contract vulnerability in the custody/auction contracts, and loss or theft of the covered artwork while held in custody, subject to the policy terms and limits in force at the time.
• Limits & exclusions — coverage is subject to per-occurrence and aggregate limits, deductibles, and exclusions in the underlying policies (for example, market value declines, loss caused by the collector's own mishandling after delivery, or events outside the policy territory). [Limits and the full exclusion list to be completed by counsel.]
• Claims — claims must be filed with the provider through the platform using the artwork's custody certificate, deposit transaction, and IPFS snapshot as evidence. [Claims intake process and provider contact to be added once the policies are bound.]
• Not a guarantee — insurance is not a guarantee of value or of reimbursement in every scenario. The platform is not itself an insurer and does not guarantee payment of any claim.

Disputes
