Full Context: https://forum.synapseprotocol.com/d/5-sip-05-recalibrating-syns-emissions/4

Summary:

• Harmony: unchanged at 30k SYN/ week (reduced once ONE rewards go live)
• Fantom: Reduce from 95.5k SYN to 78k SYN/week with a mandate to adjust it if necessary, including increasing emissions back, to keep average TVL above $50m (see rationale in original proposal)
• Polygon: Reduce by 10% per week over three weeks, from 95.5k to 70k SYN/week
• BSC: Reduce by 12% per week over three weeks, from 111,475/week to 77k SYN/week
• Avalanche/Arbitrum: Reduce by 14% per week over three weeks, from 111,475 to 70k SYN/week for nUSD pools and 140k to 89k SYN/week for nETH pool
