How Caper approaches this
Caper has no delegation primitive, so there is nothing to activate by signing – but the eligibility question does not disappear, and its answer is unusual enough to be worth stating plainly.
Casting a ballot requires a proof of at least one of that caper's tokens; holding is the entry ticket. Weight is then the product of two factors the ballot records at vote time – the voter's token balance and their balance of that caper's soulbound vote token – multiplied and divided by the vote-token supply and the token's circulating supply. It is not settled at vote time, though. The ballot stores those readings and no weight; the weight is computed afterwards, when the permissionless crystallize crank folds the ballot and credits the smaller of the balance recorded at the cast and the balance still held at the fold (fold_ballot_batch, contracts/logic/src/lib.rs).
Activation here is therefore not a thing you do once and leave standing: selling down after casting shrinks the ballot you have already cast. Voting mints exactly one vote token to the voter (VOTE_MINT), alongside a flat 100 XRD vote fee paid into the caper's treasury, and it is the only mint a member can reach. Buying or selling on the caper's bonding curve minted vote tokens too, at 0.01 per XRD of gross value on each leg, until the redeploy of 11 September 2026 removed the trade-side mint (contracts/logic/src/lib.rs).
Two consequences follow directly. First, the ballot's snapshot counts its own mint in both the voter's vote-token balance and the supply it divides by, so a first ballot always carries weight: with ballots the only source, a snapshot taken before the mint would score every member's first ballot at zero and no caper's first proposal could pass. Holding without voting, by contrast, activates nothing. A bag bought on the curve, swapped or transferred in, or accrued as the founder's cut out of other people's buys carries no vote tokens until its holder casts a ballot.
There is no founder allocation at creation to hold – founder_token_balance starts at zero and fills one purchase at a time (contracts/core/src/caper_dao.rs) – and withdrawing that cut mints no vote tokens, so a founder who has never voted is exactly the holder this case describes (see what a founder can and cannot take). Activation exists, and you activate by participating – by voting – rather than by delegating. Second, holdings are a multiplicative factor rather than the whole story: a large balance with no participation history multiplies by zero, and a long participation history with no holdings does too. Neither leg carries a vote alone.
What this does not do is solve the denominator problem described above – it relocates it. Caper's denominator is the token's circulating supply, which is knowable on-ledger rather than dependent on how many holders remembered to sign something. See Voting for the mechanics and what is a caper for the surrounding model.
