1 · EscrowThe seller deposits the tokens in the OTC contract and names a price in ETH, USDG or NLYRA, with an expiry. Partial fills are allowed above the minimum the seller chose. A bid is the mirror image: you escrow USDG, WETH or NLYRA and name the amount of NLYRA (or USDG, or ETH) you want for it.
2 · Atomic fillA buyer pays the ask. In the same transaction the tokens leave the escrow to the buyer and the payment reaches the seller. Nobody holds anyone's money in between.
3 · Burn0.5% of the payment goes to the NLYRA buyback burner: ETH is forwarded on the spot, NLYRA is burned directly, USDG is swapped to ETH for the burner. The other 99.5% is the seller's.
