ARPA Staking
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
ARPA Staking locks ARPA on Ethereum to support the network’s threshold-signature nodes. Community stakers receive rewards through auto-delegation and face a 14-day unlock, while node operators can lose rewards for malicious DKG behavior. DefiLlama reported about $0.20M of staking on 2026-08-16, only 0.20% of the $100M materiality floor. The network and token risks merit full review at scale, but current capacity is institutionally unusable.
- TVL sustained above $100M for 30 days
The research file
Mechanism applicability
ARPA uses groups of nodes to jointly produce BLS threshold signatures. Community holders stake ARPA into the Ethereum staking contract and are auto-delegated to nodes; a node operator must stake at least 500,000 ARPA and maintain network service. Rewards compensate community participation and node tasks rather than representing a claim on external assets.
Control, loss and exit applicability
ARPA documentation says malicious node behavior during distributed-key generation can forfeit 50% of the node’s monthly auto-delegation reward and harm community rewards. Community users may initiate exit at any time but wait 14 days before claiming unlocked tokens. Token price, contract correctness, node operation, reward policy and the unlock queue remain the holder’s loss and liquidity perimeter.
Current observation and perimeter
The DefiLlama API read on 2026-08-16 classified ARPA Staking as a Staking Pool and reported approximately $0.20M, entirely as Ethereum staking TVL rather than ordinary protocol TVL. ARPA’s current network-parameter page identifies the Ethereum token and staking contracts, matching the registry perimeter.
Why the materiality dossier still applies
Current staking value is about 0.20% of the $100M floor, so an advised-client position would dominate observed capacity and its 14-day exit before institutional diligence could justify use. Reopen only after staking TVL remains above $100M for 30 days, then review contract roles and upgrades, node concentration and uptime, slashing and reward history, token liquidity and proposed-size unlock execution.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls
The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
| Chain | Verdict | Grade | Control constraint |

| Ethereum | Approved | sovereign | No sequencer, no upgrade key, no operator who can be compelled — rule changes require social consensus. |
